Abstract

An all-CMOS single chip architecture of a frequency-hopped spread spectrum (FH/SS) transceiver is presented. The transceiver implements complete modem functions spanning a tuned RF front-end to a digital binary frequency-shift keying (FSK) modulator/demodulator, all operating from a 3-V supply. This FH/SS transceiver is intended for use in a wide variety of indoor/outdoor portable wireless applications in the 902-928 MHz ISM band [1]. System features such as dual antenna/branch diversity, fast frequency hopping, and adaptive power control are incorporated into the transceiver architecture to achieve robust wireless digital data transmission over multipath fading channels. This paper describes the architectural features of the transceiver and surveys several of the key building blocks which have been completed to date
