GENERAL DESCRIPTION

The ADRF5532 is an integrated RF, front-end multichip module

designed for time division duplex (TDD) applications. The device

operates from 2.3 GHz to 2.7 GHz. The ADRF5532 is configured

with a low-noise amplifier (LNA) and a high-power, silicon, single

pole double throw (SPDT) switch.

In the receive operation at 2.6 GHz, the LNA offers a low noise

figure (NF) of 1.2 dB and a high gain of 35.5 dB with a third order

input intercept point (IIP3) of ?4 dBm.

In the transmit operation, the switch provides a low insertion loss of

0.7 dB and handles a long-term evolution (LTE) average power of

36.5 dBm for a full lifetime operation (8 dB peak to average ratio

(PAR)) and 39 dBm for a single event (<10 sec) LNA protection

operation.
