Explanation
Equivalent Circuit
1
AGC IN1
1.5
Input pin of IF signal.
1pin is same phase and 2pin is opposite
phase at balance input.
In case of single input, 1pin or 2pin should
be grounded through capacitor.
2
AGC IN2
1.5
3VAGC
0 to 5
Automatic gain control pin.
This pin’s bias govern the AGC output level.
Minimum gain at VAGC = 0 V
Maximum gain at VAGC = 5 V
Recommend to use by deviding AGC voltage
with externally resistor (ex. 100 k
).
4
Vcc1
5.0
Power supply pin of IF down convertor block.
Must be connected bypass capacitor to
minimize ground impedance.
5OSC
OUT
4.0
Output pin of Oscillator frequency.
Connected to PLL symthesizer IC’s input pin.
6
GND
0.0
Ground pin.
Must be connected to the system ground
with minimum inductance.
Ground pattern on the board should be
formed as wide as possible.

OSC B2
2.4
8OSC C1
4.6
9OSC C2
4.6

OSC B1
2.4
Internal oscillator consist in balance amplifier.
7 and 8pins, 9 and 10 pins should be
externally connected to oscillate with active
feedback loop.
Connected LC resonator between 7pin and
10pin.
