GND Ground. Connect to the board’s ground plane using low-inductance layout techniques.
2 OUT_A
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.
5, 13, 16,
25, 32
V
CC
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.
8 IN_A
Second-Attenuator Input. Internally matched to 50 over the operating frequency band. Connect to
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.
11 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.
15 R
SET1
First-Stage Amplifier Bias-Current Setting. Connect to GND through a 1.2k resistor.
17 R
SET2
Second-Stage Amplifier Bias-Current Setting. Connect to GND through a 2k resistor.
20 OUT
RF Output. Internally matched to 50 over the operating frequency band. Requires a DC-blocking
capacitor and a shunt-matching capacitor.
26 AMP_IN
Amplifier Input. Internally matched to 50 over the operating frequency band. Connect to
ATTN_OUT through a DC-blocking capacitor.
29 ATTN_OUT
Attenuator Output. Internally matched to 50 over the operating frequency band. Connect to
AMP_IN through a DC-blocking capacitor.
35 IN
RF Input. Internally matched to 50 over the operating frequency band. Connect to a 50 RF
source through a DC-blocking capacitor if the second attenuator is not used.
— EP
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.
