AD6458ARS中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

The AD6458 is a 3 V, low power receiver IF subsystem for operation at input frequencies as high as 400 MHz and IFs from 5 MHz up to 50 MHz. It is optimized for operation in GSM, DCS1800 and PCS1900 receivers. It consists of a mixer, IF amplifier, I and Q demodulators, a phase-locked quadrature oscillator, precise AGC subsystem, and a biasing system with external power-down.
