Designing A Single Ended UHF BJT Mixer Using the ADS Software

Objectives:
• A simple UHF Mixer operating at 430.0 MHz is designed. The RF signal at 430.0
MHz is down converted into IF frequency of 20.0 MHz.
• The mixer is targeted to have no attenuation (conversion gain of 0dB) and an
operating noise figure of less than 10dB.
• The design steps are divided into 5 parts. These are the DC biasing of the mixer
circuit, S-parameters measurement for RF and IF, input matching, output matching
and final design verification.
