A single-chip 2.4 GHz RF transceiver LSI with a wide-range FV conversion demodulator

Abstract

A single-chip RF transceiver LSI for 2.4 GHz-band GFSK applications uses a 0.5 /spl mu/m BiCMOS which provides 23 GHz f/sub T/. The transceiver consumes 34.4 mA in TX mode (PA, PLL) and 44.0 mA in RX mode (LNA, IR mixer, filters, limiter, RSSI, demodulator, PLL). It has a linear FV conversion demodulator with wide input-frequency range.
