RFDA2046

Digital Controlled Variable Gain Amplifier

1800MHz to 2800MHz

The RFDA2046 is a digital controlled variable gain amplifier

featuring high linearity over the entire gain control range with

noise figure less than 5.2dB in its maximum gain state. The gain

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

mode control interface (SPI). The RFDA2046 is packaged in a

small 6.0mm x 6.0mm leadless laminate MCM, which contains

plated through thermals vias for ultra-low thermal resistance. This

module is easy to use with no external matching components

required.
