Abstract :
This work presents the design and characterization of medium voltage LDMOS transistors developed for 5-6 GHz power amplifier applications. Power transistors of different size have been fabricated in a 0.25 μm BiCMOS technology of IHP microelectronics and were characterized using a load/source pull measurement system. The optimum load and source impedances obtained for a 1.1 mm device provide the basis for a 6 GHz power amplifier design with an output power of 27.8 dBm in saturation and 25.1 dBm at 1 dB power compression. The peak drain efficiency of this power amplifier is 25.5% with a small signal gain of 8.1 dB.
