DESIGN AND REALIZATION OF A K-BAND HEMT MIXER
HEBA AHMED SHAWKY MOHAMED;
Abstract
In this thesis the design and realization of a K-band HEMT mixer is presented. The mixer design used a single gate HEMT that features reasonable conversion gain of about 5-6 dB and good isolation between input and output ports.
The design involved first the experimental characterization and modeling of the equivalent circuit of the chosen HEMT.
The analysis of the mixer circuit followed the "harmonic-balance technique" implemented on the nonlinear simulator of HP's "Microwave Design System" package (MDS).
The matching circuits were designed using coupled microstrip lines for the input circuit at RF = 20 GHz and Lo = 18 GHz, and low pass filter prototype microstrip lines for the output circuit at IF = 2 GHz.
The designed mixer was finally tested and experimental results were compared with theoretical ones.
