Texas Instruments TRF2001P ISM Band Multiprotocol & Wi-SUN RF FEM
Texas Instruments TRF2001P ISM Band Multiprotocol and Wi-SUN RF Front-End Module (FEM) is a high-performance RF FEM for low-power wireless applications in sub-1GHz industrial, scientific, and medical (ISM) bands operating over an 820MHz to 1054MHz frequency range. The TRF2001P requires minimal external BOM and includes functions such as a range-extender power amplifier (PA) and a low noise amplifier (LNA), transmit-receive antenna switch, 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 TRF2001P increases the link budget and extends range in wireless systems by providing high output power with the integrated PA, beyond the capabilities of a WMCU or transceiver, and by improving 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 Texas Instruments TRF2001P is operational over a wide 3.1V to 4.25V supply range, with digital controls compatible with 1.6V to 3.3V CMOS logic levels.
