It features exceptional linearity with noise figure less than 5.0dB in its maximum High Linearity Power Control gain state. The gain of the 6-bit digital step attenuator is programmed with a serial mode control interface (SPI). The RFDA2125 is packaged in a small 5.2mm x 5.2mm leadless laminate MCM, which contains plated through thermal vias for ultra-low thermal resistance.
