Receiver

Technical Documentation

The receiver is a dual–conversion superheterodyne using two intermediate
frequencies, 45 MHz and 450 kHz.

The RF signal from the duplexer RX port is applied to the RF amplifier. The
amplifier has 18 dB gain and 1,5 dB noise figure.

Next the signal is filtered with Z321. The filter is followed by a single balanced
diode mixer, which has 6 dB conversion loss.

After the mixer signal is filtered with the crystal filter Z350, which has 7,5 kHz
bandwidth. Next the IF signal is amplified by V380. From the amplifier the
IF–signal is applied to the second mixer.

The second mixer, the LO buffer transistor, IF amplifier and quadrature
detector are all integrated in the circuit N370. The second LO frequency,

44.55 MHz, is third harmonic of the VCTCXO frequency . LO signal is realized
with tank circuit C372 and L371. After the mixer the 450kHz IF signal is
filtered with ceramic filter Z370. The IF amplifier output signal is phase
shifted by resonance circuit. After this the signal is fed to a quadrature
detector.

Signal DAF is low pass filtered by R372 and C379. The DAF, RSSI and 2nd
IF signal (450 kHz) are fed to the audio/logic unit.

RX Synthesizer

The first injection frequency for receiver is generated by a digital phase
locked loop (PLL). The output frequency of the loop (LO) is obtained from
a voltage–controlled oscillator (VCO) G530. The VCO output signal is
amplified by RX–LO–buffer and fed to the receiver mixer . The injection level
required by the receiver mixer is about +3 dBm. In addition, the signal is
feeded back to the dualsynthesizer circuit N820.

The overall divisor of the chain is selected according to the desired chan­nel.

The internal dividers of N820 are programmed with 17 bits, which are
transferred serially on the SDAT (synthesizer data) line from the processor
into an internal shift register also located in N820. Data transfer is timed with
SCLK clock pulses.

The divided frequency is compared with a highly stable reference frequency
by a phase comparator in the PLL circuit. The phase comparator controls the
VCO frequency by means of a DC voltage through the loop filter so as to keep
the divided frequency applied to the phase comparator equal to the fixed
reference frequency.

The reference frequency is 12,5 kHz. This reference frequency is obtained
from voltage controlled crystal oscillator (VCXO or VCTCXO). Oscillator
frequency is 14.85 MHz. The VCXO frequency is divided by 1188.

RX loop filter

Phase comparator output is pin 3. If the VCO frequency is too high, the
output goes low and discharge integrator capacitor C521. After this, the DC
control voltage and the VCO frequency will decrease.

NHN–3N

Technical Documentation

If the VCO frequency is too low, the output goes high and charge the
integrator capacitor C521. Thereafter the DC control voltage and the VCO
frequency will go up.

Output pulses from the phase detector have to be supplied to the loop filter.
The function of the integrator is to convert positive and negative pulses to DC
voltage. The remaining ripple and AC components are filtered in the lowpass
filter.

TX Synthesizer

The transmitter synthesizer generates a frequency modulated transmitter
signal for the transmitter section. The modulated TX injection frequency is
generated in TX–VCO (G430). The TX modulated TX signal is amplified in
TX–buffer before the transmitter.

TX Loop Filter

Output pulses from the phase detector N820 pin 17 have to be supplied to
the loop filter. The integrator, which is constituted of R420 and C421,
converts positive and negative pulses to DC voltage. The remaining ripple
is filtered in the low–pass filter.

RF Block

Transmitter

The transmitter is realized with a power amplifier module. The modulated RF
signal from the TX synthesizer is applied to the 50 ohm input of the module.
The power level is controlled by the voltage supplied to the pin 1. Zener diode
V642 protects the module against too high control voltages (>4.5 V).
Amplifier module has two pairs of output pins ( pins 10, 11 and 14,15 ).
Amplified RF signals are compined symmetrically and fed through a
low–pass filter to the duplex filter. The harmonics of the transmitter are
reduced by the duplex filter. A voltage proportional to the output power is
rectified from a directional coupler by DC–biased Schottky diode V640. This
rectified voltage is fed to a differential amplifier which consists of transistor
V650. The reference voltage is filtered from the PWM signal by TXC line. The
differential amplifier adjusts the control voltage so that the reference voltage
and the voltage proportional to the output power are equal. The transmitter
is switched on when TXE goes high (logic 1), which enables the transmitter
power control circuit by transistor V653. When the transmitter is inactive
(TXE low) the RF level from the transmitter is reduced below –57 dBm.

Regulators

The voltage regulators for RF parts consist of the transistors V310, 31 1, 313
and 314. The first regulator (V310, 311) provides the operating voltage for
the receiver, PLL circuit and RX–VCO buffer. The other one is used to
regulate the operating voltage of the RX–VCO. These regulators are
realized using discrete transistors because the output noise has to be very
low. The 3.3 V reference voltage (VREF) is fed from the logic module. TX
synthesizer gets the supply voltage via a switch which is realized using
transistors V411 and V410. The switch is controlled by the digital TXS–line
from the logic module.

AFC function

The transceiver unit is equipped with AFC function, i.e. it uses the incoming
receive signal from base station as a frequency reference. The control loop
consists of the receiver, the IF counter in the NIPA, CPU, an 8–bit D/A
converter in the NIPA and the VCTCXO, which is used as a reference
oscillator for the synthesizer.

The 2nd IF signal (450 kHz) from receiver is fed to the NIP A. The IF counter
counts the received frequency. If the frequency differs from programmed
value, CPU adjusts the frequency of the VCXO by changing output voltage
of the D/A converter. This adjustment continues until the desired receive
frequency is achieved. AFC is not active during a channel scan and below
–90 dBm RX signal level.
