Product Description
RFMD's RFDA2026 is a digital controlled variable gain amplifier featuring
high linearity over the entire gain control range with a noise figure less
than 4.1dB in its maximum gain state. The gain of the 6-bit digital step
attenuator is programmed with a serial mode control interface (SPI). The
RFDA2026 is packaged in a small 6.0mm x 6.0mm leadless laminate
MCM, which contains plated through thermal vias for ultra-low thermal
resistance. This module is easy to use with no external matching compo-
nents required.
