0.38 GHz to 15 GHz RxVGA

The ADL6332 RxVGA provides an interface from LNA/beam former/ Rx front end to RF analog-to-digital converters (RF-ADC). Each ADL6332 IC is composed of a balun, two differential RF amplifiers with bypass attenuators, and a digital step attenuator (DSA) to provide suitable receiver performance in a 24-terminal, 4.0 mm x 4.0 mm LGA package.

Serial-port interface (SPI) control is available to configure RF signal path or to optimize supply current vs. performance.

An integrated RF balun is used to provide a single-ended input over 0.38 GHz to 8.0 GHz (ADL6332-A) or 1.0 GHz to 15.0 GHz (ADL6332-B) with good impedance match.
