1. Frequency Confi guration

The receiver utilizes double conversion. The first IF is

49.95MHz 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.

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 (D201, D202, D203
and D204) and a BPF (L418 and L419), and is then amplifi ed
by the RF amplifi er (Q407).

The resulting signal passes through a BPF (L413, L414

and L440) and goes to the mixer. These BPFs are adjusted
by variable capacitors (D431, D410, D403, D404 and D405).
The input voltage to the variable capacitor is a regulated
voltage output from the DC amplifi er (IC811).

1. 频率构成

接收部采用二次变频超外差方式。第一中频为 49.95M 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. 接收部系统

接收部系统的如图 2 所示。

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

( D201、D202、D203 和 D204)，然后通过 B P F ( L418 和 L419)，
并且被射频放大器 (Q407) 放大。

此信号通过 BPF(L413、L414 和 L440) 然后进入混频。这些

B P F 被可变电容器 ( D431、D410、D403、D404 和 D405) 调整。
输入可变电容器的电压被经直流放大器 ( I C811) 的电压输出
调整。
