Overview
The ADRF5547BCPZN is a dual-channel, integrated RF front-end multichip module designed by Analog Devices Inc. This component is specifically tailored for time division duplexing (TDD) applications and operates within the frequency range of 3.7 GHz to 5.3 GHz. It features a cascading two-stage low noise amplifier (LNA) and a high power silicon, single-pole, double-throw (SPDT) switch. This configuration makes it ideal for wireless infrastructure, particularly in TDD massive multiple input and multiple output (MIMO) and active antenna systems.
