General Description

The ADRF5545A is a dual-channel, integrated radio frequency (RF), front-end multichip module designed for time division duplexing (TDD) applications that operates from 2.4 GHz to 4.2 GHz.

The ADRF5545A 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 1.45 dB and a high gain of 32 dB at 3.6 GHz with an output third-order intercept point (OIP3) of 32 dBm (typical).
