GND
Ground. Connect to the boards ground plane using low-inductance layout techniques.
2
OUT_A
Attenuator A RF Output. Internally matched to 50I over the operating frequency band. This pin,
if used, requires a DC block. If this attenuator is not used, the pin can be left unconnected.
4, 31
RTNA, RTNB
Attenuator Ground Returns. These pins require a cap to ground and need to be placed close
to each pin. This capacitor centers the RF band of operation. See the Typical Operating
Characteristics section.
5
V
CC
Attentuator A Power Supply. Bypass to GND with a capacitor and a resistor as shown in the
Typical Application Circuit.
8
IN_A
Attenuator A RF Input. Internally matched to 50I over the operating frequency band. This pin,
if used, requires a DC block. If this attenuator is not used, the pin can be left unconnected.
11
CTRL
Attenuator Control Voltage Input. Except in the test mode where no voltage can be applied
to this pin. V
CC
 must be present unless using a current-limiting resistor as noted in the
Applications Information section.
