Abstract: A Solid State Power Amplifier (SSPA) for powering a single element of a multi-element antenna, the SSPA comprising: an RF amplifier, having a signal amplifying path that includes preamplifier, driver amplifier and a power output stage; an Electronic Power Conditioner (EPC) for providing a variable value of DC voltage for powering the power output stage of the RF amplifier; a control ASIC for receiving an input power signal of the RF amplifier for providing a voltage control signal to the EPC to determine the value of the DC voltage, the control ASIC addressing an EEPROM holding a collection of control words that define output values of a control output signal for varying values of said input power, such that the value of the DC voltage to the power output stage is varied so as to control the gain compression of the RF amplifier for varying values of input power in order to maintain constant amplifier linearity.
