RF Output and DC BIAS for the second amplifier (AMP2).
See Application Circuit for off-chip components.
RF input for the second amplifier (AMP2).
This pin is DC coupled. An off-chip
DC blocking capacitor is required.
Input and output of the 6-bit digital attenuator (6-Bit DAT).
These pins are DC coupled and matched to 50 Ohms.
Blocking capacitors are required. Select value based
on lowest frequency of operation.
RF output for the first amplifier (AMP1)
This pin is matched to 50 Ohms.
