Product Description
Dual 5-Bit Parallel Control
Interface
RFMD's RFDA0035 is a dual-channel, digitally controlled variable gain amplifier fea-
turing high linearity over the entire 32 gain control steps. It features independent
channel power-up enable, independent channel current adjustability for optimizing
DC versus IP3 and a 200 differential input and output impedance.
