The dual-channel, integrated radio frequency (RF) receiver front-end module is designed for time division duplexing (TDD) and massive multiple-input and multiple-output (mMIMO) applications that operate in the 2.4 GHz - 4.2 GHz frequency range.

As an authorized distributor, Mouser Electronics is focused on the rapid introduction of new products and technologies, giving customers an edge and helping speed time to market. Over 800 semiconductor and electronic component manufacturers count on Mouser to help them introduce their products into the global marketplace. Mouser's customers can expect 100% certified, genuine products that are fully traceable from each manufacturer.

The Analog Devices ADRF5545A, available from Mouser Electronics, is configured in dual channels with a cascading two-stage gallium arsenide (GaAs) low noise amplifier (LNA) and a high-power silicon single-pole, double-throw (SPDT) switch. The device features single supply operation and interface for CMOS control signals, simplifying inclusion in multi-channel hardware designs with repeatable performance over the complete system.

The ADRF5545A offers high RF power handling capability (averaging 40 dBm lifetime) together with high integration and advanced circuit architecture that minimizes the need for external components, making it ideal for 5G mMIMO antenna interfaces.
