Firmware Loader). The KFL.exe exists in the KPG-D1/D1N installed holder.

(2) Set the baud rate to "auto" or 1152000, 576000, 115200,

and 57600. (3) Set the firmware to be upgrade by file name item. (4) Enter the Firmware programming mode by using section

“2.2.2 How to Enter Each Mode”. Then, the yellow LED on

the transceiver light and "FIRMWARE PROG" is displayed. (5) Check the connection between the transceiver and the per-

sonal computer, and make sure that the transceiver is in

the Program mode. (6) Press “Write” button in the window. When the transceiver

starts to receive data, the “LOADING” display lights. (7) If writing ends successfully, the checksum is calculated

and a result is displayed. (8) If you want to continue programming other transceivers, re-

peat step (4) to (7).

Note:

If write is perfomed by KFL, Firmware programming mode will start automatically even if Firmware programming is set to disable in the programming software.

2.4 CIRCUIT DESCRIPTION

2.4.1 Overview

The NX-5300 is a UHF Analog FM & Digital Portable transceiver designed to operate in the frequency range of 450 to 520MHz (F2,F3,K2,K3) or 380 to 470MHz (F5,F6,K5,K6). The unit consists of a receiver, a transmitter, a phase-locked loop (PLL) frequency synthesizer, a digital control unit, and a power supply circuit.

2.4.2 Frequency Configuration

The receiver is a double-conversion super-heterodyne using a first intermediate frequency (IF) of 49.95MHz and second IF of

2.25MHz. Incoming signals from the antenna are mixed with the local signal from the PLL circuit to produce the first IF of 49.95MHz. This is then mixed with the 47.7MHz second local oscillator output to produce the 2.25MHz second IF. The transmit signal frequency is generated by the PLL VCO, and modulated by the signal from the DSP. It is then amplified and fed to the antenna.

2.4.3 Receiver System

2.4.3.1 RF Circuit

The receive signal from antenna switch (D350, D370 and D371) is amplified by a RF amplifier (Q530) and passes through the bandpass filter (L523, L533 and L520) to remove unwanted signals. The signal is then fed to the 1st mixer (Q500).

2.4.3.2 IF Circuit

The first IF signal is passed through a four-pole monolithic crystal filter (XF670) to reject adjacent channel signals. The filtered first IF signal is amplified by the first IF amplifier (Q670 and Q660) and then applied to the IF system IC (IC600). The IF system IC provides a second mixer, second PLL, AGC and A/D converter. The second mixer mixes the first IF signal with the 47.7MHz of second local oscillator output and produces the second IF signal of

2.25MHz. The second IF signal is then be fed into an A/D converter, generates the I and Q data. This data is in the form of SSI (Serial Synchronous Interface), and sent to the DSP (IC702).

2.4.3.3 Audio Amplifier Circuit

Audio processing (high-pass filter, low-pass filter, de-emphasized and so on) at Analog FM mode and decoding at Digital mode are processed by DSP. SSI signal from DSP is converted to audio signal at IC902. The signal goes to amplifier (IC904 or IC905). While INTAMT is High, IC904 is activated and audio is heard from internal speaker.

2.4.4 Transmitter System

2.4.4.1 Audio Band Circuit

The signal from microphone is amplified and converted to digital signal by IC902. IC902 includes AGC function. Digital signal is transferred to IC702 through SSI.

2.4.4.2 Baseband Circuit

The audio signal transferred from IC902 is processed at IC702. Voice signals of 300Hz or lower and frequencies of 3kHz or higher are cut off and an audio range 300Hz to 3kHz is extracted. The audio signal is then pre-emphasized in FM mode and synthesized with the signals, such as QT and DQT, as required, and is transferred to PLL Frequency Synthesizer block. The DTMF and MSK baseband signals are also generated by IC702. In Digital mode, the audio signal is converted to the 4-Level FSK baseband signal and is transferred to PLL Frequency Synthesizer block. The output level according to the transmit carrier is fine-adjusted according to each modulation method.

2.4.4.3 Drive and Final Amplifier

The signal from the TX PLL is amplified by pre-drive amplifier (IC300 and Q310). The output of the pre-drive amplifier is amplified by the drive amplifier (Q320) and final amplifier (Q330) to 5W (1W when the power is low). IC300 is MMIC. Q310, Q320 and Q330 are MOS FET. The output of the final amplifier is then passed through the harmonic filter (LPF) and antenna switch (D350, D370 and D371) and applied to the antenna terminal.

2.4.4.4 APC Circuit

The APC circuit always monitors the current flowing through the drive amplifier (Q320) and final amplifier (Q330). The APC keeps a current constant. The voltage drop at R400 and R402 is caused by the current flowing through the RF power amplifier and this voltage is applied to APC circuit. Output voltage from APC controls the VGG of Q310, Q320 and Q330 to keep the current constant. The change of power high/ low is carried out by the change of the reference voltage.

2.4.5 PLL Frequency Synthesizer

2.4.5.1 TCXO (X700)

TCXO (X700) generates a reference frequency of 19.2MHz for the PLL frequency synthesizer. This reference signal is buffered by Q700 and IC700. And it is distributed to TX PLL (IC100), RX PLL (IC200), IF IC (IC600), GPS/Bluetooth (IC850), and IC702. The frequency adjustment is achieved by adjusting a D/A converter (IC901) output in the voltage of the control terminal of TCXO.

2.4.5.2 VCO F2,F3,K2,K3 types

There are TX VCO and RX VCO. The TX VCO (Q140) generates the carrier for the transmitter. The VCO oscillation frequency range is 450 to 520MHz. The transmit frequency range is 450 to 520MHz. The RX VCO (Q240) generates the 1st local signal for the receiver. The VCO oscillation frequency range is 400.05 to 470.05MHz. The 1st local signal frequency range is 400.05 to 470.05MHz. The VCO oscillation frequency is determined by voltage control terminals "CV" and "ASSIST". The voltage control terminal "CV" is controlled by PLL IC (IC100 for TX PLL, IC200 for RX PLL). The voltage control terminal "ASSIST" is controlled by the control voltage from D/A converter (IC901). For the modulation input terminal, "VCO_MOD" of TX VCO (Q140), the output frequency changes according to the applied voltage. This is used to modulate the VCO output.

F5,F6,K5,K6 types

There are TX VCO _L, TX VCO_H, RX VCO_L and RX VCO_H. The TX VCO_L (Q160) and TX VCO_H (Q140) generates the carrier for the transmitter. The oscillation frequency range of TX VCO_L is 380 to 413.5MHz. The oscillation frequency range of TX VCO_H is 413.5 to 470MHz. The transmit frequency range is 380 to 470MHz. The RX VCO_L (Q260) and RX VCO_H (Q240) generates the 1st local signal for the receiver. The oscillation frequency range of RX VCO_L is 330.05 to 363.55MHz. The oscillation frequency range of RX VCO_H is 363.55 to

420.05MHz. The 1st local signal frequency range is 330.05 to 420.05MHz. The VCO oscillation frequency is determined by voltage control terminals "CV" and "ASSIST". The voltage control terminal "CV" is controlled by PLL IC (IC100 for TX PLL, IC200 for RX PLL). The voltage control terminal "ASSIST" is controlled by the control voltage from D/A converter (IC901). For the modulation input terminal, "VCO_MOD" of TX VCO_H (Q140) and TX VCO_L (Q160), the output frequency changes according to the applied voltage. This is used to modulate the VCO output.

2.4.5.3 PLL IC

There are TX PLL IC and RX PLL IC. PLL ICs compare the difference in phases of the VCO oscillation signal and the TCXO reference frequency. And it returns the difference voltage to the VCO CV terminal and realizes the "Phase Locked Loop". This allows the VCO oscillation frequency to accurately match (lock) the desired frequency. When the frequency is controlled by the PLL, the frequency convergence time increases as the frequency difference increases when the set frequency is changed. To supplement this, the MPU is used before control by the PLL IC to bring the VCO oscillation frequency close to the desired frequency. As a result, the VCO CV voltage does not change and is always stable at approx. 2.5V. The desired frequency is set for the PLL IC by the MPU (IC702) through the 3-line "SDO1", "SCK1", "/PCS_R" serial bus for RX PLL and "SDO1", "SCK1", "/PCS_T" serial bus for TX PLL. The MPU monitors through the "PLD_R" and "PLD_T" signal line, whether the PLL IC is locked or not. If the VCO does not lock to desired frequency (unlock), the "PLD_R" and "PLD_T" logic is low.

2.4.6 Control Circuit

The control circuit consists of MPU/DSP (IC702) and its peripheral circuits. IC702 mainly performs the following;

(1) Switching between transmission and reception by PTT signal input. (2) Reading system, zone, frequency, and program data from the memory circuit. (3) Sending frequency program data to the PLL. (4) Controlling the audio mute circuit by decode data input.

2.4.6.1 MPU

The MPU/DSP (IC702) is 32-bit RISC processor and fixed floating-point VLIW DSP, equipped with peripheral function. This MPU operates at 288MHz (MAX) clock and 3.3V /1.8V/ 1.2V DC. Controls the flash memory, Mobile DDR, the receive circuit, the transmitter circuit, the control circuit, and the display circuit and transfers data to or from an external device.

2.4.6.2 Memory Circuit

Memory circuit consists of the MPU (IC702) and the Mobile DDR (IC703), the flash memory (IC705). The flash memory has capacity of 512M-bit that contains the transceiver control program for the MPU and stores the data. It also stores the data for transceiver channels and operating parameter that are written by the FPU. This program can be easily written from external devices. The Mobile DDR has capacity of 512 M-bit. The MPU copies the program to the Mobile DDR from the flash memory. The MPU is used as a work area Mobile DDR.

Flash Memory Note:

The flash memory stores the data that is written by the FPU (KPG-D1/D1N), tuning data (Deviation, Squelch, etc.), and firmware program (User mode, Test mode, Tuning mode, etc.). This data must be rewritten when replacing the flash memory.

Mobile DDR (static memory)

Note:

Mobile DDR is used as a work area of the MPU.

2.4.6.3 LCD

The LCD is controlled using parallel interface from the MPU (IC702).

2.4.6.4 Key Detection Circuit

Keys are detected using I/O Expander IC (IC708). If pressed key is detected by IC708, it is informed to the MPU (IC702) through serial line.

2.4.6.5 Low Battery Warning

The battery voltage is divided using R40 and R41 and is detected by A/D converter (IC900). When the battery voltage falls below the voltage set by the Low battery warning adjustment, the red LED blinks to notify the operator that it is time to replace the battery. If the battery voltage falls even more (approx. 5.8V), a beep sounds and transmission stops.

2.4.6.6 DSP

The DSP circuit consists of a MPU/DSP (IC702) and processes the baseband signal. The DSP operates at 288MHz (MAX) clock, the I/O section operates at 3.3V/1.8V and the core section operates at 1.2V. The DSP carries out the following processes:

• 4 Level FSK processing

• Analog FM pre-emphasis/de-emphasis

• Transmit/receive audio filtering processing

• Microphone amplifier AGC processing

• Audio mute processing

• Modulation level processing

• Active Noise Reduction

• Voice recording/playback processing

• Voice announce processing

2.4.7 Power Supply Circuit

The battery voltage (+B) is provided from battery terminal. The battery voltage passes through the 3.15A fuse (F1), and goes to RF final amplifier, AVR ICs (IC31, IC82, IC801, IC36, IC63, IC65, IC64), DC/DC converter (IC33), transistor (Q32, Q71 through the 1A fuse (F2)), and voltage detector IC (IC20). Voltage detector (IC20) watches battery voltage. If the battery voltage is enough higher than 5.6V, detector outputs High. Then, IC31 (31BU) outputs 3.1V, and IC32 (12BU) outputs 1.2V, and Q31 is turned on. When the VOL SW is turned on, SB1 becomes high (battery voltage). The DC/DC (IC33) operates if both SB1 and output of detector are high. IC33 (38M) outputs 3.8V, and A30 (12M) outputs 1.2V. Then, IC34 (18M) and IC37 (18BT) outputs 1.8V. Then, IC80 (30M) outputs 3.0V, and IC38 (33BT) and IC35 (33M) and IC81 (33OPT) outputs 3.3V. Then, IC39 (33A) outputs 3.3V, and IC82 (50A) outputs 5.0V. Then, IC701 (18M_3) outputs 1.8V, and Q71 (53AF) is turned on. Voltage detector (IC704) watches IC33 (38M) output voltage. If the 38M output voltage is enough higher than 3.5V, detector outputs High. As a result, the MPU/DSP operate. The SBC signal becomes High after the MPU/DSP operates, and IC61 (33C), IC36 (50C), IC63 (50VCO) and Q32 (SB2) are turned on. When SD_EN signal becomes High, IC30 (33SD) operates. When 5UC signal becomes High, IC801 (50U) operates. When TXC signal becomes High, IC65 (50T) operates. IC65 (50T) is turned on in transmit mode. When RXC signal becomes High, IC64 (50R) operates. IC64 (50R) is turned on in receive mode. Switches are controlled by the MPU/ DSP. When the VOL SW is turned off /PSW signal becomes Low. After detecting /PSW signal, the MPU/DSP changes SBC signal to Low. The 50C is fed to IC60 (200C). IC60 (200C) is the DC/DC boost converter. IC60, D60, C64 consist of a voltage quadruple. The 200C circuit then outputs approximately +20VDC.

The battery voltage is low and the transceiver is not usable to make calls.

DISASSEMBLY

3.1 Precautions for Waterproof

• Do not remove the black sheet from the reverse side of the transceiver (refer to the illustration below). Removal of this sheet decreases the waterproof efficiency of the transceiver and may cause malfunctions if water seeps into the transceiver.

• The orange packing material on the reverse side of the transceiver is important with respect to the waterproof efficiency of the transceiver. Do not place stickers or other materials on or around the packing material shown in the figure, or on the reverse side of the battery pack. Doing so will impair the waterproof efficiency of the transceiver and may cause it to break down. Additionally, in order to prevent damage to the packing material, do not allow it to come in contact with foreign materials.

3.2 Precautions for Disassembly
