Abstract
Digitally-enhanced cordless telephone (DECT) is a standard for residential cordless telephony and wireless local loop. Components for this market must be low-cost and highly-integrated. This paper presents a DECT radio frequency integrated circuit (RFIC). This IC, combined with an IFIC, baseband converter, low-noise amplifier, and power amplifier form the basis for a DECT telephone. The RFIC is fabricated on a high-speed (25 GHz f/sub T/) bipolar process. The radio frequency (RF) architecture includes an upconverter transmit chain, a single downconverting receiver, a voltage controlled oscillator (VCO) and local oscillator (LO) distribution network, a low drop-out voltage regulator, and a mode controller.Keywords
