FUNCTION
Ground. Connect to the board’s ground plane using low-inductance layout techniques.
Second-Attenuator Output. Internally matched to 50
over the operating frequency band. Connect
to IN through a DC-blocking capacitor if greater than 21dB of gain-control range is required. No
connection is required if the second attenuator is not used.
Power Supply. Bypass each pin to GND with capacitors as shown in the Typical Application
Circuit. Place capacitors as close to the pin as possible.
Second-Attenuator Input. Internally matched to 50
over the operating frequency band. Connect to

IN_A
a 50
RF source through a DC-blocking capacitor if greater than 21dB of gain-control range is
required. No connection is required if the second attenuator is not used.

V CNTL
Analog Gain-Control Input. Limit voltages applied to this pin to a 1V to 4.5V range when V CC is
present to ensure device reliability.
