RFDA2026

DIGITAL CONTROLLED VARIABLE GAIN AMPLIFIER

1400MHz to 2700MHz, 6-BIT 0.5dB LSB CONTROL

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.
