Setup
Step 1: Connect Power
1a:Three power levels must be provided to the board for
V
CC
, V
EE
, and GND via the surface mount clips. Using the
split power supply mode, GND = V
TT
= V
CC
– 2.0 V.

= − 1.3 V
NOTE: For frequency domain measurements, 2.5 V
power supply is not recommended because
additional equipment (bias tee, etc.) is needed
for proper operation. The input signal has to be
properly offset to meet V
CMR
range of the
device .

Small Signal Setup
Step 2: Input Setup
2a: Calibrate VNA from 1.0 GHz to 12 GHz.
Set input level to –35 dBm at the output of the 180
°
Hybrid
coupler (input of the DUT).
Step 3: Output Setup
3a: Set display to measure S21 and record data.
Large Signal Setup
Step 2: Input Setup
2a: Calibrate VNA from 1.0 GHz to 12 GHz.
2b: Set input levels to
− 2.0 dBm (500 mV) at the input of
DUT.
Step 3: Output Setup
3a: Set display to measure S21 and record data.
