Fully-Integrated Core chip for X-Band Phased-Array T/R modules

摘要

This paper discusses the final result of development effort leading to a fully-integrated phased-array core chip. The MMIC is especially useful for active electronically-steered arrays, and integrates a full functionality including low-noise amplifier (LNA), a medium-power amplifier (MPA) matched to common high-power amplifiers (HPA) and all control functions. The design and measurement results will be discussed. The integration of an LNA and MPA makes this MMIC an ideal candidate for a two chip T/R module solution. The MMIC is realised in the 0.25μm PHEMT (PH25) process of UMS.
