Description for the TRF2001
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.
