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 functionality is required.
