The integration of radar systems has taken a long journey into the modern world. Advances in signal processing technology and integrated circuit technology have lead the way for smaller, more integrated radar systems. Specific to the hardware side of a radar, the RF generation and detection once done in one location in the radar is now being replaced by small sub-elements which combine RF generation and detection at the element level. This work describes a power amplifier that can be used at the element level. The design methodology for a single stage amplifier in a Silicon Germanium Bipolar process covering 5-14 GHz is discussed. Simulation results and measurement results closely match and show peak power outputs of 25 dBm and peak power-added efficiencies (PAE) of approximately 32 %.
