Why in the world somebody
just tell me what is the usable
power !!!

Linear Output Power, Plinear
Intermod Level, -25 dBc
Spectral Regrowth, -30 dBc
Amplifier Output Signal
The most important output power parameter is the linear output power, Plinear.
The Plinear rating of an amplifier is the maximum output power at which:
-25 dBc intermod can still be achieved with a two-tone intermod test
-30 dBc spectral regrowth on a single carrier digitally modulated signal
Plinear is achieved at 3 dB back from Psat.
Thus an 1000W Psat SSPA produces 500W Plinear output power

SSPA Technology
• GaAs
• Nearly Class A mode of
operation.
• Lower Power Devices than GaN
• Better Linearity at low output
power levels.
• P-linear = P1 - 3dB
• GaN
• Class AB mode.
• Much higher power transistors.
• Same Linearity as GaAs at high
output power levels (when
linearized).
• P-linear = P-sat-3dB (linearized)
• P-linear = P-sat-4dB (not linearized)
