The TRF2001P is a high-performance RF front-end module (FEM) designed to be paired with wireless microcontroller (MCU) and system-on-chip (SoC) ICs for applications primarily supporting various sub-1GHz ISM bands. The device improves the link budget by increasing the system's TX power well beyond the capabilities of the wireless MCUs and SoCs with the integrated PA and improving the RX sensitivity with the integrated LNA.

A key limitation of most wireless SoCs designed for the sub-1GHz ISM band is that the transmit (TX) output power is typically limited to about 16dBm, with very few supporting up to 22dBm. When these SoCs are used at TX powers greater than 10dBm, the spurious-free dynamic range (SFDR) often deteriorates. The increased spurious levels require additional filtering and metal shielding in many cases, to comply with regulatory requirements such as those set by the FCC and ETSI standards. The TRF2001P allows the SoCs to operate at lower output power levels by providing additional RF gain and high TX output power capability that exceed 27dBm, thus reducing the SoC's spurious levels, and often eliminating the need for additional filtering and shielding.

With integrated, fully matched 50Ω RF interfaces, the TRF2001P simplifies interface design to the antenna and the wireless SoCs. The digital control logic pins (CEN, CTR, and CIB) of the device are used to configure the device in TX, RX, or device powered down mode, and are compatible with CMOS levels of 1.6V to 3.3V.

The TRF2001P operates over a wide single supply voltage range of 3.1V to 4.25V and achieves 27.5dBm P_SAT on 3.3V supply. The device is available in a space-saving 4.5mm × 4.5mm, 28-pin, WQFN-FCRLF package.
