Description

The M/A-COM AM55-0024 is a dual channel IF amplifier

and digital attenuator packaged in a multi-layer multi-chip

module (MCM). Gain control is via two separate serial

logic interfaces. The part utilizes Plastic Ball Grid Array

(PBGA) interconnect technology to achieve high circuit

density and superior performance. This device is ideal for

GSM/DCS/PCS digital base station applications where high

dynamic range gain control is required.
