ADRF6521ACPZ

ADRF6521 is a dual, fully differential, low noise and low distortion variable gain amplifier (VGA). The high spurious free dynamic range over the gain range makes the device ideal for communication systems with dense constellations, multiple carriers, and nearby interferers. This device's flexibly operates from a single +5V supply or from a range of dual supplies and consumes a total supply current of 200mA. When fully disabled, it consumes 25mA typical. It is fabricated in an advanced silicon germanium BiCMOS process. It is used in application such as point-to-point and point-to-multipoint radios, baseband IQ receivers, diversity receivers, ADC drivers, instrumentation, medical etc.
