A new concept for front‐end circuit integration: From single‐ended antenna to differential‐input connection without any external balun

A new concept for a single-ended input front-end circuit design is proposed. The coupling of a single-ended low-noise amplifier (LNA) to a double-balanced cross-coupled mixer using a single-to-differential transformer is successfully implemented and then tested in the 5.725–5.825-GHz band in order to show its feasibility. Furthermore, this idea is even useful for wide-receive-band applications when the bandwidth of the LNA is designed widely. © 2005 Wiley Periodicals, Inc.
