GENERAL DESCRIPTION
mode providing 17 dB of gain at a lower current of 35 mA. The ADRF5549 is a dual-channel, integrated, RF front-end In power-down mode, the LNAs are turned off, and the device multichip module designed for time division duplexing (TDD) draws 12 mA. applications that operates from 1.8 GHz to 2.8 GHz. The In transmit operation, when RF inputs are connected to a ADRF5549 is configured in dual channels with a cascading, termination pin (TERM-ChA or TERM-ChB), the switch two-stage, low noise amplifier (LNA) and a high power, silicon provides a low insertion loss of 0.6 dB and handles a long-term single-pole, double-throw (SPDT) switch. evolution (LTE) ful lifetime average (9 dB peak to average ratio In high gain mode, the cascaded two-stage LNA and switch (PAR)) of 40 dBm and 43 dBm for a 9 dB PAR LTE single event offer a low noise figure of 1.4 dB and a high gain of 35 dB with (<10 sec) average. The device comes in a RoHS-compliant, an output third-order intercept point (OIP3) of 32 dBm typical. compact, 6 mm × 6 mm, 40-lead, lead frame chip-scale package (LFCSP).
