1) Power amplifier in overcritical C-operation.
2) Power amplifier is switched off at 2.15 V
Matching circuitry as used in the 50 Ohm-Output Testboard.
Supply-voltage dependency: 2 dB / V at 3 V with reference to 3 V.
Temperature dependency: +1 dB at -25°c and -3 dB at +85°C with reference to +25°C.
A smaller load impedance reduces the supply-voltage dependency.
A higher load impedance reduces the temperature dependency.
