CIRCUIT DESCRIPTION /

电路说明

1. Frequency Confi guration

The receiver utilizes double conversion. The first IF is

38.85MHz and the second IF is 450kHz. The fi rst local oscil-
lator signal is supplied from the PLL circuit.

The PLL circuit in the transmitter generates the neces-

sary frequencies. Fig. 1 shows the frequencies.

2. Receiver

The frequency confi guration of the receiver is shown in

Fig. 2.

2-1. Front-end RF amplifi er

An incoming signal from the antenna is applied to an RF

amplifier (Q203) after passing through a transmit/receive
switch circuit (D102 and D103 are off) and a 3-pole LC fi lter.
After the signal is amplifi ed (Q203), the signal is fi ltered by
a band pass fi lter (a 3-pole LC fi lter) to eliminate unwanted
signals before it is passed to the fi rst mixer.

The voltage of these diodes are controlled by to track the

MCU (IC403) center frequency of the band pass fi lter. (See
Fig. 2)

1. 频率构成

接收部采用二次变频超外差方式。第一中频为 38.85M H z，

第二中频为 450K H z。第一本振频率信号由锁相环电路 ( P L L )
提供。

发射部由锁相环电路直接产生所需要的频率。图 1 显示各

种频率。

2. 接收部

接收部的频率构成如图 2 所示。

2-1. 前端射频放大器

从天线输入的信号经过收发转换电路 ( D102 和 D103 断开 )

和三极管 L C 滤波器后，在射频放大器 ( Q203) 处放大。信号
被放大后 ( Q203)，在通过第一混频器之前，经过带通滤波器
( 一个三极管 L C 滤波器 ) 滤波来消除不要的信号。这些变容
二极管的电压由带通滤波器的 MCU(IC403) 中心频率控制。( 参
