RF front end module aims at massive MIMO designs
The ADRF5545A RF front end module from Analog Devices is now being shipped by Mouser Electronics. 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 2.4GHz – 4.2GHz frequency range.
The device 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.
It 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 40dBm lifetime) together with high integration and advanced circuit architecture that minimizes the need for external components, making it ideal for 5G mMIMO antenna interfaces
