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.
