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-indB
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.
