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.
