Ground. Connect to the board’s ground plane using low-inductance layout techniques.
Attenuator A 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.
Power Supply. Bypass to GND with capacitors and resistors as shown in the Typical
Application Circuit.
Attenuator A 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.
Analog Attenuator Control Input. V
tor, as noted in the Applications Information section. Limit voltages applied to this pin to a
+1.0V to +4.0V range with V
Attenuator B 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.
Attenuator B 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.
Exposed Pad. Internally connected to GND. Solder evenly to the board’s ground plane for
proper operation.
