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要的频率。图 1 显示各

种频率。

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 oscil-
lator signal is supplied from the PLL circuit.

The PLL circuit in the transmitter generates the neces-

sary frequencies. Figure 1 shows the frequencies.

2. Receiver System

The receiver system is shown in Figure 2.

2-1. Front End (RF AMP) Circuit

The signal coming from the antenna passes through the

transmit/receive switching diode circuit (D604, D605, D606
and D608), passes through a BPF (L717 and L718), and is
amplifi ed by the RF amplifi er (Q705).

The resulting signal passes through a BPF (L711, L712

and L713) and goes to the mixer. These BPFs are adjusted
by variable capacitors (D703, D704, D705, D706 and D707).
The input voltage to the variable capacitor is regulated by
voltage output from the DC amplifi er (IC19).

2-2. First Mixer

The signal from the front end is mixed with the fi rst local

oscillator signal generated in the PLL circuit by Q704 to pro-
duce a fi rst IF frequency of 49.95MHz.

The resulting signal passes through the XF701 MCF to

cut the adjacent spurious and provide the optimum charac-
teristics, such as adjacent frequency selectivity.

2. 接收部系统

接收部系统的如图 2 所示。

2-1. 前级 ( 射频放大器 ) 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

( D604、D605、D606 和 D608)，然后通过 B P F ( L717 和 L718)，
并且被射频放大器 (Q705) 放大。

此信号通过 BPF(L711、L712 和 L713) 然后进入混频。这些

B P F 被可变电容器 ( D703、D704、D705、D706 和 D707) 调整。
输入可变电容器的电压被经直流放大器 ( I C19) 的电压输出调
整。

2-2. 第一混频器

前端的信号与 P L L 电路产生的第一本振信号在 Q704 混频，

生成 49.95MHz 频率的第一中频信号。

生成的信号通过 XF701 MCF。
