This pin is DC coupled and requires VCC through a bias inductor sized accordingly to provide a high pass transformation with a series capacitor. Ground connection. Keep traces physically short and connect immediately to ground plane for best performance. 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. RF input pin. This pin is DC coupled. Ground connection. Keep traces physically short and connect immediately to ground plane for best performance. 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.
