Analog Devices Inc. ADRF5519 20W Receiver Front End

Analog Devices ADRF5519 20W Receiver Front End is a dual-channel, integrated RF, front-end multi-chip module designed for time-division duplexing (TDD) applications that operate from 2.3GHz to 2.8GHz. The ADRF5519 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 high gain mode, the cascaded two-stage LNA and switch offer a low noise figure (NF) of 1.0dB and a high gain of 35dB at 2.6GHz with an output third-order intercept point (OIP3) of 32dBm (typical). In low gain mode, one stage of the two-stage LNA is in bypass, providing 14dB of gain at a lower current of 36mA. In power-down mode, the LNAs are turned off and the device draws 12mA.

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. The Analog Devices ADRF5519 comes in a RoHS-compliant, compact, 6mm × 6mm, 40-lead LFCSP package.
