ADRF6520ACPZ

The ADRF6520ACPZ from Analog Devices is a matched pair of fully differential low noise and low distortion programmable filters and variable gain amplifiers (VGAs). Each channel is designed to reject large, out-of-band interferers while boosting the wanted signal, reducing bandwidth and resolution requirements for analog-to-digital converters (ADCs).

Key electrical specifications include a maximum gain of 53 dB, a continuous gain control range of 60 dB, and a noise figure of 10.5 dB. The device operates at a frequency of 1.25 GHz with a P1dB compression point of 14 dBm. It also offers an I/Q bandwidth up to 720 MHz, with a flatness of >1250 MHz when the filter is bypassed.

This RF amplifier is suitable for applications such as point-to-point and point-to-multipoint radios, baseband IQ receivers, diversity receivers, and ADC drivers. It is housed in a 32-LFCSP (5x5) package and is designed for surface mount applications.

The device operates on a single 3.3 V supply and includes a power-down feature. The filter corners, enable, and DC offset correction loop are programmable via a serial peripheral interface (SPI).
