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 os-
cillator is supplied from the PLL circuit.

The PLL circuit in the transmitter generates the neces-

sary frequencies.

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 450kHz。第一本振频率信号由锁相环电路提供。

发射部由锁相环电路直接产生所需的频率。

2. Receiver System

The receiver system is shown in Figure 2.

2-1. Front End (RF Amplifi er) Circuit

The signal coming from the antenna passes through the

transmit/receive switching diode circuit (D101, D102, and
D103) and a BPF (L210), and is then amplifi ed by the RF am-
plifi er (Q204).

The resulting signal passes through a BPF (L207 and

L208) and goes to the mixer. These BPFs are adjusted by
variable capacitors (D201 and D202). The input voltage to
the variable capacitor is a regulated voltage output from the
DAC (IC300).

2-1. 前端 ( 高频放大器 ) 电路

从天线接收的信号进入发送 / 接收转换开关二极管电路

( D101、D102 和 D103)，然后通过 B P F ( L210)，并且被射频放
大器 (Q204) 放大。

此信号通过 BPF(L207 和 L208) 然后进入混频。这些 BPF 被

可变电容器 ( D201 和 D202) 调整。输入可变电容器的电压被
经 DAC(IC300) 的电压输出调整。
