The ADRF5549 is a dual-channel, integrated, RF front-end multichip module designed for time division duplexing (TDD) applications that operates from 1.8 GHz to 2.8 GHz. The ADRF5549 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 of 1.4 dB and a high gain of 35 dB 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 mode providing 17 dB of gain at a lower current of 35 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 0.6 dB and handles a long-term evolution (LTE) full lifetime average (9 dB peak to average ratio (PAR)) of 40 dBm and 43 dBm for a 9 dB PAR LTE single event (<10 sec) average. The device comes in a RoHS-compliant, compact, 6 mm × 6 mm, 40-lead, lead frame chip-scale package (LFCSP).

Applications

  • Wireless Infrastructure
  • TDD massive multiple input and multiple output (MIMO) and active antenna systems

Product Detail

The ADRF5549 is an integrated, dual-channel receiver front end, ideally suited for time division duplexing (TDD) wireless infrastructure applications. The ADRF5549 consists of a high power switch and a two-stage low noise amplifier (LNA) on each channel.

This user guide describes the ADRF5549-EVALZ evaluation board, designed to easily evaluate the features and performance of the ADRF5549. A photograph of the evaluation board is shown in Figure 1.

The ADRF5549 and the ADRF5545A are pin compatible receiver front ends that cover different frequency bands and that use the same evaluation printed circuit board (PCB). However, the ADRF5545A requires a few external matching components (see UG-1589 for additional information).

The ADRF5549 data sheet provides full specifications for the ADRF5549. Consult the ADRF5549 data sheet in conjunction with this user guide when using the evaluation board.
