Notes:
1. The Maximum OIP3 values are calculated based on Load pull
measurements on approximately 100 different impedances using
Maury’s Load pull test system.
2. Measurements are conducted on 0.010 inch thick ROGER 4350. The
input reference plane is at the end of the RFin pin and the output
reference plane is at the end of the RFout pin as shown in Figure 21.
3. Gamma Load for maximum OIP3 with biasing of 3V 50mA, 3.5V
50mA, 4V 50mA, 4.5V 50mA, 5V 40mA, 5V 50mA and 5V 60mA from
500 MHz to 3.5GHz are available upon request.
