Function
Description
Interface Schematic
1RF OUT
RF output pin. This pin is DC coupled and requires VCC through a bias
inductor sized accordingly to provide a high pass transformation with a
series capacitor.
2GND
Ground connection. Keep traces physically short and connect immediately
to ground plane for best performance.
3GC
Analog gain control pin. This pin controls the gain of the IC. Minimum gain
occurs at VGC<0.4V and maximum gain is achieved with VGC=2.0V. 50dB
of linear gain control with little variation of input P1dB is available.
4RF IN
RF input pin. This pin is AC coupled.
5GND
Ground connection. Keep traces physically short and connect immediately
to ground plane for best performance.
6VCC
Power supply. This pin should be connected to a regulated supply and
requires a bypass capacitor. Voltage is supplied through this pin to the first
stage collector; this voltage also controls the bias. Gain may be tuned by
adjusting the value of the feed inductor.
