A 22.4 GHz TransceiverA 2.4 GHz Transceiver RF Front-end for ISM-Band Digital Wireless CommunicationsSen-You Liu and Huey-Ru Chuang National Cheng Kung Universityhis paper is a comprehensive presentation of the design, implementation, and measured performance of a 2.4 GHz transceiver RF front-end for ISM-band digital wireless communication. A dual frequency conversion strategy is employed in this RF front-end (2.4 - 2.47 GHz). The 1st and 2nd IFs are 280 MHz and 55 MHz, respectively. The TDD duplexing method is adopted in this module, controlled by T/R switch. A Class-A two-stage power amplifier, a preamplifier, single-ended resistive mixer and low noise amplifier are designed and combined with suitable IF RFICs, filters and switches to form a transceiver RF front-end (not including frequ……
