RFDA4005

6-Bit, Digital Controlled Variable Gain Amplifier

50MHz to 4000MHz

RFMD’s RFDA4005 is a digitally controlled variable gain amplifier

featuring high linearity over the entire gain control range with

noise figure less than 6dB in its maximum gain state. The gain of

the 6-bit digital step attenuator is programmed with a serial mode

control interface. The RFDA4005 is packaged in a small 5.2mm x

5.2mm leadless laminate MCM which contains plated through

thermal vias for ultra-low thermal resistance. The footprint for this

module is directly compatible with a 5mm x 5mm QFN. This

module is easy to use with no external matching components

required.
