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). In low gain mode, one stage of the two-stage LNA is in bypass, providing 16 dB of gain at a lower current of 36 mA. In power-down mode, the LNAs are turned off and the device draws 12 mA.
In transmit operation, when RF inputs are connected to a termination pin (TERM-ChA or TERM-ChB), the switch provides a low insertion loss of 0.65 dB and handles long-term evolution (LTE) average power (9 dB peak to average ratio (PAR)) of 40 dBm for full lifetime operation and 43 dBm for single event (<10 sec) LNA protection operation.
The device comes in an RoHS compliant, compact, 6 mm × 6 mm, 40-lead LFCSP package.
