RFDA0057 RFDA0057Digital Controlled Variable Gain DIGITAL CONTROLLED VARIABLE GAIN AMPLIFIER 400MHz TO 2700MHz Package: MCM 32-Pin, 7.0mm x 7.0mm Features Dual Channel VGA Frequency Range 400MHz to 2700MHz Full Internal Matching and No External Bias Inductors Two 6-Bit Digital Step Attenuators 12-Bit SPI Serial Control Programming High Channel Isolation = 50dBc Max Gain = 18.5dB at 900MHz Gain Control Range = 31.5dB (0.5dB Step Size) High OIP3/P1dB = +37dBm/19dBm at 900MHz Single + 5V Supply Small 32-Pin, 7.0mm x 7.0mm, MCM Power-up Programming Functional Block Diagram Product Description RFMD’s RFDA0057 is a dual-channel, digital controlled variable gain amplifier featuring high linearity over the entire gain control range with noise figure less than 7dB in its maximum gain state. The gains of two 6-bit digital step attenuators are programmed with a serial mode control interface (SPI). The RFDA0057 is packaged in a small 7.0mm x 7.0mm leadless laminate MCM, which contains plated through thermal vias for ultra-low thermal resistance. This module is easy to use with no external matching components required.
