Title ADS-based RF mixer design

Abstract

Information age led to the rapid development of communication technology, communications, electronics, increasing use of RF and microwave circuits for industrial production, the industrial sector eyeing high-frequency circuits.As a high-frequency circuit mixer system is an important component of the process of the entire circuit ,and also plays an important role in processing.The quality of the mixer directly affects the performance of the circuit. This article describes in some detail the mathematical principles of the mixer and performance specifications, and according to the device or structural classification. This paper systematically studied the single-balanced passive mixer. According to design specifications given topic, design simulation using ADS software to meet the reservation target, and simulation results are appropriate analysis.
