Design and Experimental Performance of Diplexing MMIC Distributed Amplifier

摘要

An MMIC distributed amplifier with dual band frequency response and diplexing functionality is designed and measured. Using a band-pass artificial transmission line, two frequency bands, Spanish satellite broadcast TV band (11.7–12.5 GHz) and the mobile TV link (10.0–10.7 GHz), can be amplified and extracted at different physical ports. Experimental results exhibit quite good agreement with simulations and demonstrate the viability of these amplifiers in MMIC technology.
