The ADRF5545A is a dual-channel, integrated radio frequency current of 36 mA. In power-down mode, the LNAs are turned (RF), front-end multichip module designed for time division off and the device draws 12 mA. duplexing (TDD) applications that operates from 2.4 GHz to In transmit operation, when RF inputs are connected to a 4.2 GHz. The ADRF5545A is configured in dual channels with termination pin (TERM-CHA or TERM-CHB), the switch a cascading two-stage low noise amplifier (LNA) and a high provides a low insertion loss of 0.65 dB and handles long-term power silicon single-pole, double-throw (SPDT) switch. evolution (LTE) average power (9 dB peak to average ratio In high gain mode, the cascaded two-stage LNA and switch (PAR)) of 40 dBm for ful lifetime operation and 43 dBm for offer a low noise figure (NF) of 1.45 dB and a high gain of single event (<10 sec) LNA protection operation. 32 dB at 3.6 GHz with an output third-order intercept point The device comes in an RoHS compliant, compact, 6 mm × (OIP3) of 32 dBm (typical). In low gain mode, one stage of the 6 mm, 40-lead LFCSP package. two-stage LNA is in bypass, providing 16 dB of gain at a lower
