A 1.9 GHz single-chip IF transceiver for digital cordless phones

Portable communication equipment, such as cellular phones and digital cordless phones, employ as many ICs as possible instead of discrete devices to be competitive in size, weight, and power dissipation. Although a UHF single-chip transceiver has been reported, it is still difficult to achieve that integration level for L-band cordless phones, such as the Personal Handy Phone System (PHS). This article describes a 1.9 GHz single chip IF transceiver IC for digital-cordless phones.
