RFDA4005 Datasheet Digital Controlled Variable Gain Amplifier

Manufacturer: RF Micro Devices (now Qorvo)

Overview: RFDA4005 6-Bit, Digital Controlled Variable Gain Amplifier 50MHz to 4000MHz RFMD’s RFDA4005 is a digitally controlled variable gain amplifier featuring high linearity over the entire gain control range with noise figure less than 6dB in its maximum gain state. The gain of the 6-bit digital step attenuator is programmed with a serial mode control interface. The RFDA4005 is packaged in a small 5.2mm x 5.2mm leadless laminate MCM which contains plated through thermal vias for ultra-low thermal resistance. The footprint for this module is directly patible with a 5mm x 5mm QFN. This module is easy to use with no external matching ponents required.
