A new GaAs variable gain amplifier MMIC with a wide-dynamic-range and low-voltage-operation linear attenuation circuit

Masahiko Inamori; Kaname Motoyoshi; Takahiro Kitazawa; Katsushi Tara; Masahiro Hagio

A 40 dB-dynamic-range variable gain amplifier designed for CDMA cellular phones has been developed. A wide dynamic range variable gain amplifier under low control voltage of 2.0 V compatible with high linearity and low distortion characteristics essential for CDMA is realized by the new gain control technique. It greatly contributes to the high performance and small size RF circuits of CDMA cellular handsets.


radio frequency integrated circuits symposium | 2000

An ultra low current consumption two step power control driver MMIC with self current control for wideband-CDMA handsets

M. Nakayama; Kaname Motoyoshi; Takahiro Kitazawa; Katsushi Tara; Masahiro Hagio

This paper presents a two step power control driver MMIC for wideband-CDMA handsets. It has the self current control function coupled with the output power level. It realizes low current consumption of 12 mA at an average output power level (Pave) without any sacrifice of high performance at the high output power level. It greatly contributes to the realization of compact and low power consumption W-CDMA handsets.
