Notes
1. The device is adjusted to provide nominal load power into a 50 Ω load. The device is switched off and a 6 : 1 load
replaces the 50 Ω load. The device is switched on and the phase of the 6 : 1 load is varied 360 electrical degrees
during a 60 seconds test period.
2. The power amplifier can be matched to PCS and/or DCS/PCS operation through optimization of the matching circuit;
see Application Note (tbf).
3. Isolation can be improved to −20 dBm (typical) with a pin diode switched in the DCS output matching circuit.
