A low cost 900MHz single-chip cordless telephone receiver is presented. This IC is suitable for 900MHz portable wireless applications including cordless telephone. Receiver functions are programmed through a serial port interface (SPI). The receiver IC can be operated either as a single conversion or dual conversion receiver with a 12dB SINAD of -11SdBm. Power consumption is rated at 20mA of supply current operating from 1.8V to 2.8V. This IC utilizes a k4pm BiCMOS process and features an LNA, hvo mixers, IF amplifier, I F limiter, demodulator, VCO, crystal reference oscillator, PLL, and an 80 bit SPI. All of these functions have been integrated onto a 1.09mm x 1.08"(1.18mm') die.

This paper presents an overview of both the basic building blocks and process technologies associated with silicon ICs for personal wireless communications. The technical challenges to achieve higher levels of RF monolithic integration at a low cost and with low power dissipation in battery-powered portable transceivers are presented. Specific emphasis will be given to applications in the 1 to 2 GHz range of carrier frequencies.
