Function and Application
Internal Equivalent Circuit
1
RF IN1
1.46
Input Signal of IF signal.
1 pin is the same phase and 2 pin is opposite
phase at balance input.
In case of single input, 1pin or 2pin should
be grounded through capacitor (ex. 10 nF).

VAGC
0 to 3.5
Automatic gain control pin.
This pn's bias govern the AGC output level.
Minimum gain at VAGC = 0V
Maximum gain at VAGC = 3.5 V

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 IN1
2.6
Input pin of Oscillator signal.
5pin is same phase and 6pin is opposite
phase as balance input.
In case of single input, 5pin or 6 pin should
be grounded through capacitor (ex. 10 nF).
