ADRF5519BCPZN

ADRF5519 is a dual-channel, integrated RF, front-end multichip module designed for time division duplexing (TDD) applications that operates from 2.3GHz to 2.8GHz. It is configured in dual channels with a cascading two stage low noise amplifier (LNA) and a high power silicon single pole, double-throw (SPDT) switch. In transmit operation, RF inputs are connected to a termination pin (ANT-CHA or ANT-CHB connected to TERM-CHA or TERM-CHB, respectively). The switch provides a low insertion loss of 0.5dB and handles a long-term evolution (LTE) average power (9dB peak to average ratio (PAR)) of 43dBm for full lifetime operation. It is used in application such as wireless infrastructure, TDD massive multiple input and multiple output and active antenna systems, TDD-based communication systems etc.
