RFDA0016

DIGITAL CONTROLLED VARIABLE GAIN AMP

50 TO 1000MHZ, 6 BIT 0.5DB LSB CONTROL

RFMD’s RFDA0016 is a digital controlled variable gain amplifier featuring high lin-

earity over the entire gain control range. The 6-bit digital step attenuator is pro-

grammed via a serial mode control interface. The RFDA0016 is packaged in a

6mmx6mm leadless laminate MCM with plated through thermal vias for low ther-

mal resistance. The amplifier’s bias chokes and DC blocks are external allowing for

optimum performance over specific bands within 50MHz to 1000MHz.
