【 摘 要 】

References(11)Cited-By(1)A Ku-band transceiver chip (TR chip), which can be used for the phased array system, is presented in this paper. It includes a high power amplifier (HPA), a low noise amplifier (LNA) and two switches. The transmitting chain can provide over 2 watt (W) RF output power and 14 dB gain, meanwhile the receiving chain shows less than 3 dB noise figure and 25 dB gain in the frequency range of 15 to 17.5 GHz. A novel switch based on GaAs pHEMT process is also proposed, which can handle over 2 W RF output power without sacrificing the performance of the receiving chain. The size of the TR chip is 3 mm × 3 mm.
