This paper presents a Medium Power Amplifier (MPA) for X-Band Phased Array RADAR applications in 0.25 mu m SiGe technology. The MPA is designed such that it achieves high output power and low noise simultaneously that enables its use in Transmitter/ Receiver (T/R) core module as a Low Noise Amplifier (LNA). The MPA achieves 23.6dB peak gain and 17.3dB maximum output power at 10GHz with a power consumption of 190mW. Its input and output is matched in a 7 GHz of bandwidth, while its mean Noise Figure (NF) is about 3dB throughout the defined bandwidth. According to authors' knowledge, this work presents state-of-the-art wideband MPA performances in literature, with 7GHz of operational bandwidth and 17.3dBm output power.
