Design and Experimental Performance of Diplexing MMIC Distributed Amplifier

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...

Description
Summary: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.
