1. Overview

The NX-320 is a UHF portable transceiver designed to

operate in the frequency range of 450 to 520MHz (K,K2,K3)
or 400 to 470MHz (K4,K5,K6,E,E2,E3). The unit consists of a
receiver, transmitter, phase-locked loop (PLL) frequency syn-
thesizer, baseband parts, power supply, and control circuits.

2. Frequency Confi guration

The receiver is a double-conversion superheterodyne

using the first intermediate frequency (IF) of 49.95MHz
and the second IF of 450kHz. Incoming signals from the
antenna are mixed with the local signal from the PLL circuit
to produce the fi rst IF of 49.95MHz. This is then mixed with
the 50.4MHz second local oscillator output to produce the
450kHz second IF. The transmit signal frequency is gener-
ated by the PLL VCO, and modulated by the signal from the
DSP. It is then amplifi ed and fed to the antenna.

3. Receiver System

3-1. RF circuit

An incoming RF signal from the antenna terminal is

passed through the antenna switch (D102, D103, D105 and
D106) and then the band-pass fi lter (L212, L213 and L214).
The band-pass fi lter is adjusted by a variable capacitor. The
input voltage to the variable capacitor is regulated by the

voltage output from the D/A converter (IC4). The signal is
amplifi ed by an RF amplifi er (Q202), and passed through the
band-pass fi lter (L207, L208 and L209). The resulting signal
is applied to the fi rst mixer (Q201), where it is mixed with
the first local oscillator signal output from the frequency
synthesizer to produce the fi rst IF (49.95MHz).
