3 Description

The TRF2001 is a high-performance RF front-end

module (FEM) for low-power wireless applications

in sub-1GHz industrial, scientific, and medical (ISM)

bands operating over an 860MHz to 930MHz

frequency range. The TRF2001 requires minimal

external BOM and includes functions such as a

range-extender power amplifier (PA) and a low

noise amplifier (LNA), transmit-receive and antenna

switches, antenna port low pass filter, and a linear-in-

dB RF power detector, for a cost-effective design in a

space-saving 4.5mm × 4.5mm QFN-28 package.

The TRF2001 increases the link budget and allows

range extension in wireless systems by providing

high output power with the integrated PA, beyond the

capabilities of a WMCU or transceiver, and improves

the receiver sensitivity with a low noise figure LNA.

The integrated power detector can be used for system

calibration or to monitor the power being delivered to

the antenna. The device features fully matched, 50Ω

RF interfaces for ease of use and design flexibility.

The TRF2001 is operational over a wide, 3.1V to

4.25V supply range, with digital controls that are

compatible with 1.6V to 3.3V CMOS logic levels.
