Analysis of discontinuity effects in development a fully integrated millimeter wave receiver front end

This paper analyzes two of the most important discontinuity effects of the transmission line in MMIC design. Both the marginal effect and discontinued ground plane have been considered to avoid deterioration of the circuit. A fully integrated receiver front end MMIC chip which is constructed with a three stage low noise amplifier cascaded with a resistive mixer for millimeter wave down conversion application has been achieved by using above mentioned analysis results of discontinuity effects. This multifunctional chip operates at RF frequency range from 24GHz to 40GHz, IF frequency up to 1GHz.
