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
N.C.
No Internal Connection. This pin can be left open or ground.
Note: If a common layout is desired to support the MAX19794, connect a 0402 capacitor to
ground on each of these pins.
5
V
CC
Attenuator A Power Supply. Bypass to GND with a capacitor and 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 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.
