Ground. Connect to the board’s ground plane using low-inductance layout techniques.
Second-Attenuator Output. Internally matched to 50
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
a 50
required. No connection is required if the second attenuator is not used.
Analog Gain-Control Input. Limit voltages applied to this pin to a 1V to 4.5V range when V
present to ensure device reliability.
First-Stage Amplifier Bias-Current Setting. Connect to GND through a 1.2k
Second-Stage Amplifier Bias-Current Setting. Connect to GND through a 2k
RF Output. Internally matched to 50
capacitor and a shunt-matching capacitor.
Amplifier Input. Internally matched to 50
ATTN_OUT through a DC-blocking capacitor.
Attenuator Output. Internally matched to 50
AMP_IN through a DC-blocking capacitor.
RF Input. Internally matched to 50
source through a DC-blocking capacitor if the second attenuator is not used.
Exposed Pad. This pad affects RF performance and provides heat dissipation. This pad MUST be
soldered evenly to the board’s ground plane for proper operation.
