CIRCUIT DESCRIPTION

NXR-710

1. Outline

The NXR-710 is a VHF repeater operating in the 136~

174MHz frequency range.

2. TX-RX unit

TX-RX unit (X57-7940-10) consists of the following cir-

cuit.

(1) Internal/external reference circuit (2) Transmitter reference 16.8MHz PLL circuit (3) Transmitter main PLL circuit (4) Modulation level adjustment circuit (5) Front-end circuit (6) 1st-Mixer circuit (7) IF circuit (8) Receiver PLL circuits (9) AVR circuits (10) Other circuits

2-1. Internal/External reference circuit

The internal reference circuit consists of X500, Q502, Q504 and D505. The output of 19.2MHz VCTCXO (X500) is fed to buffer ampliﬁ er Q502. The higher harmonic wave is attenuated by the LPF. This reference signal is fed to IF IC (IC304) as the 2nd Local signal through the Tripler.

The internal reference signal is amplified by Q504 to achieve the needed level for PLL ICs. That signal is divided

by a Wilkinson divider. The divided signal is fed to the PLL IC for the receiver. Another signal is fed to the transmitter reference 16.8MHz PLL IC through PIN diode switch (D505) which switches the Internal or external reference.

The external reference circuit consists of CN500, Q501, Q503, IC500, IC501, D503 and D504. The external reference signal (10MHz/0dBm) input from CN500 is fed to buffer ampliﬁ er Q501 and is ampliﬁ ed by Q503. Q503 is a dual gate MOS-FET. The output of ampliﬁ er (Q503) is detected by D503 and that DC voltage is amplified by IC500 (B/2). The ampliﬁ ed DC voltage is compared to the reference voltage by IC500 (A/2). The difference of voltages is ampliﬁ ed by IC500 (A/2) and is fed to the gate-2 terminal of Q503. The voltage of the Q503 gate-2 terminal is controlled automatically to constantly maintain the power output of amplifier (Q503). The output of ampliﬁ er (Q503) is fed to the transmitter reference 16.8MHz PLL IC through the PIN diode switch (D504) which switches the Internal or External reference.

The PIN diode switches (D504, D505) are controlled by the I/O expander IC (IC805 Pin15). The I/O expander IC is controlled by the MCU which is in the Control unit (X53-449). If internal reference is selected by FPU, the I/O expander IC outputs an “H” status. This signal sets power switch Q506 to ON. Then D505 is activated.

If external reference is selected, the I/O expander IC outputs an “L” status. This signal sets power switch Q500 to ON. Then D504 is activated.

2-2. Transmitter reference 16.8MHz PLL circuit

The transmitter reference 16.8MHz PLL circuit produces the reference frequency signal for the Transmitter Main PLL circuit and modulates the low-frequency components.

The circuit consists of IC600, IC601, IC602, IC603, IC604, Q601, Q602, Q603, and X600.

The VCXO (X600) signal enters the buffer ampliﬁ er Q603 and is ampliﬁ ed by Q602. The higher harmonic wave is attenuated by the LPF and returns to IC602. Its phase is compared with that of the reference frequency 5kHz.

VCO

■

The TX VCO circuit consists of two VCOs (VCO A X58508: Q352, VCO B X58-508: Q353). Those VCOs generates a transmit carrier. VCO A Q352 produces a transmitter frequency from 136.000MHz to 154.995MHz. VCO B Q353 produces a transmitter frequency from 155.000MHz to

174.000MHz.

Those VCO oscillation frequencies are determined by two systems of voltage control terminals: “CV” and “TXASSIST”.

The voltage control terminals, “CV” and “TXASSIST”, are controlled by the PLL IC (X58-508: IC300) and MCU (X53-449: IC20) and the output frequency changes continuously according to the applied voltage. For the modulation input terminal, “MO”, the output frequency changes according to the applied voltage.

minal and realizes the “Phase Locked Loop” for the return control. 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 MCU 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. 3.0V.

The desired frequency is set for the PLL IC by the MCU (X53-449: IC20) through the 3-line “SPSD0”, “SPSCLK0”, “/TXPCS” serial bus. Whether the PLL IC is locked or not is monitored by the MCU through the “LDT” signal line. If the VCO is not the desired frequency (unlock), the “LDT” logic is low.

2-4. Modulation level adjustment circuit

The Modulation level adjustment circuit adjusts the modulation waveform balance. This circuit consists of IC804, IC603, IC604, IC605 and IC606.

The modulating signal comes from the Control unit (X53-449) through the interface connector (CN800 Pin 14). The modulating signal is produced by the modulation lowpitched tone to the transmitter modulation 16.8MHz PLL circuit and adds the high-pitched modulation to the transmitter main PLL.

IC804 is an electronic volume control IC. It has 8 electronic volume control circuits. The modulation level adjustment circuit uses 2 electronic volume control circuits in IC804. The 1st electronic volume control circuit adjusts the modulating signal and is fed to IC603 and the 2nd electronic

CIRCUIT DESCRIPTION

provides a second mixer, AGC ampliﬁ er, and RSSI (Received Signal Strength Indicator).

The second mixer mixes the ﬁ rst IF signal with the 57.6 MHz of the second local oscillator output and produces the second IF signal of 450kHz.

The second IF signal is passed through the ceramic ﬁ lter (CF401, CF402 and CF403) to reject the adjacent channel signal. The ﬁ ltered second IF signal is ampliﬁ ed by the second IF ampliﬁ er (IC404) and AGC ampliﬁ er (IC403).

The signal from the AGC ampliﬁ er is input to the AD converter (X53-449: IC20) through the ceramic ﬁ lter (CF400) and operational ampliﬁ er (IC400 and X53-449: IC20).

2-8. Receiver PLL circuit (SUB unit)

VCO

■

RX VCO circuit consists of two VCOs (VCO A X58507: Q352, VCO B X58-507: Q353). Those VCOs generate a 1st local signal. For the VCO oscillation frequency, the 1st local signal is 194.05 to 232.05MHz. (VCO A:

194.05~213.05MHz, VCO B: 213.05~232.05MHz)

Those VCO oscillation frequencies are determined by two systems of voltage control terminals: “CV” and “RXASSIST”.

The voltage control terminals, “CV” and “RXASSIST”, are controlled by the PLL IC (X58-507: IC300) and the MCU (X53-449: IC20) and the output frequency changes continuously according to the applied voltage.

PLL IC (X58-507: IC300)

■

PLL IC compares the differences in phases of the VCO oscillation frequency and the VCTCXO reference frequency, returns the difference to the VCO CV terminal and realizes the “Phase Locked Loop” for the return control. 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 MCU 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. 3.0V.

The desired frequency is set for the PLL IC by the MCU (X53-449: IC20) through the 3-line “SPSD0”, “SPSCLK0”, “/RXPCS_TR” serial bus. Whether the PLL IC is locked or not is monitored by the MCU through the “LDR” signal line. If the VCO is not the desired frequency (unlock), the “LDR” logic is low.

CIRCUIT DESCRIPTION

3-2. CM coupler circuit

The CM coupler circuit is a line for detecting forward wave and reﬂ ected wave. Forward wave is detected by D3, and is converted into DC voltage. If an abnormal antenna load is connected, reflected wave is detected by D4 and converted into DC voltage.

3-3. Filter circuit

This circuit removes harmonics from the transmitter output and sends ﬁ ltered signals to the antenna.

3-4. APC circuit

The automatic transmission power control (APC) circuit stabilizers the transmitter output power at a pre-determined level. DC voltage from the CM coupler circuit is ampliﬁ ed by the DC ampliﬁ er IC202 (1/2). IC202 (2/2) compares the APC control voltage (RAMP) generated by the MCU (X53-449) and the DC ampliﬁ er IC201 (1/2, 2/2) with the output voltage from IC202 (1/2) to control the gate voltage for ampliﬁ er Q3 and ﬁ nal ampliﬁ er Q4.

3-5. High temperature detector circuit

To prevent thermal destruction of ampliﬁ er Q3 and ﬁ nal amplifier Q4, this circuit reduces the APC control voltage (RAMP) when the temperature of ampliﬁ er Q3 and ﬁ nal ampliﬁ er Q4 rises. The MCU detects the temperature with the thermistor (TH201) and controls the APC voltage (RAMP).

3-6. FAN action control circuit

The FAN action control circuit consists of the FAN and

switching transistor Q207. It is controlled by the MCU (X53-

449). If the FAN action is set to “Temperature”, the cooling fan is turned ON or OFF according to temperature. If the FAN action is set to “Continuous”, the cooling fan operates continuously, but Q207 stays ON.

3-7. AVR circuit

The 13.6V power source (+B) is provided through connector CN201 to the Final unit (X45-392 A/3). +B is connected to CN203 to supply the 13.6V power source for the TX-RX unit (X57-794). +B is a power source for the “ﬁ nal ampliﬁ er”, “drive ampliﬁ er” and fan. IC203 regulates the +B voltage to 8V. This 8V power source is connected to the FET switches Q203, Q204, Q205, and Q206. Q204 and Q206 are controlled by the “8TC” signal from the I/O expander IC which is in the TX-RX unit (X57-794). If “8TC” logic is high, Q204 and Q206 turn on and supply the 8V power source to the APC circuit and pre drive ampliﬁ ers. Q203 and Q205 are controlled by the “ASWC” signal from the I/O expander IC which is in the TX-RX unit (X57-794). If “ASWC” logic is high, Q203 and Q205 turn on and supply the 8V power source to the antenna switch circuit.

Conﬁ rmation and Alignment of Set-up to Prevent Receiver Desensitization

1. Conﬁ rmation of Duplexer alignment

The duplexer allows the Repeater to simultaneously transmit and receive. To accomplish this, in the programmed receive frequency, the transmit frequency must be notched or suppressed by 75dB or more. Additionally, on the programmed transmit frequency, the receive frequency must be notched or suppressed by 75dB or more. The following figures are examples of Duplexer alignment using a spectrum analyzer.

2. Conﬁ rmation of Repeater Desensitization

The following ﬁ gure is a Test set-up for Repeater Desensiti-

zation.

After this Test set-up is completed, confirm the Repeater

Desensitization as mentioned below.

1) Disable the repeater mode.

2) Adjust the level of the RF generator until 12dB SINAD is reached.

3) Increase the output of the RF generator by 1dB. (This increases the SINAD.)

4) Enable the repeater mode.

5) Read the SINAD level. It should not drop below 12dB SINAD. If the SINAD is less then 12dB, check the tightness of the connectors and the tuning of duplexer.
