The RFFM8228PTR7 with QFN-16-EP(2.3x2.3) RF Chips ROHS is a radio frequency chip manufactured by Qorvo. It is designed to transceiver signals with a wide frequency range of 4.0 to 5.5GHz. It features four digital output pins, four analog outputs pins, and four input pins with 50 ? return loss for improved performance. With an on-chip phase-locked loop (PLL), the chip can ultimately provide improved frequency stability and improved data transmission quality. As such, it is ideal for applications in such as pyrotechnics, avionics, wirelessly connected smart meters, automotive radar, cellular, and Wi-Fi. Moreover, the chip is designed with low pin-count and solvent-resistant QFN-16-EP package, making it especially suitable for tight-space applications.
