摘要

本文介绍了一种平面单平衡宽带混频器的设计和性能。宽带平衡器用于将平衡后的LO输入馈送到混频器电路。本设计是在8mil Roger的RO4003C基板上制造的，并使用市售的Aeroflex/Metelics MGS-904 GaAs光束引线肖特基二极管为混合提供非线性。该混频器不需要外部偏置，可以在3GHz到18GHz的频率范围(RF/LO)内工作。测量性能显示，平均转换损耗为15dB, LO-IF隔离优于24dB。该混频器可用于为各种UBW应用(如Wi-Fi, WiMAX, GSM等)设计具有成本效益的组件。

Single Balanced Mixer for UWB Applications

This paper presents the design and performance of a planar single balanced broadband mixer. A wideband balun is used to feed the balanced LO input to the mixer circuit. This design is fabricated on 8mil Roger's RO4003C substrate and commercially available Aeroflex/Metelics MGS-904 GaAs beam lead schottky diodes are used to provide non-linearity for the mixing. This mixer requires no external bias and can operate for a frequency range (RF/LO) from 3GHz to 18GHz. Measured performance shows an average conversion loss of 15dB along with LO-IF isolation better than 24dB. The mixer can be used for designing cost effective components for variety of UBW applications such as Wi-Fi, WiMAX, GSM etc.
