The millimeter-wave drive amplifier is an important component in the transceiver system. It is to provide input signal to drive the power amplifier for sufficient power output. In this paper, the driver amplifier at Ka-band is designed in 0.15um pHEMT GaAs process. The measured results are in agreement with the simulation. Based on the amplifier chip and wire bonding technique, the amplifier module is also developed and applied to the W-band receiver system.
