U2741B-NFB

Product Overview

U2741B-NFB is a UHF RF transmitter IC from Microchip Technology, organized under Semiconductors / RF and Wireless / RF Transmitters. It is intended for generating or modulating RF signals in wireless transmitters, remote-control systems, telemetry equipment, RFID/RKE designs, low-power sensor nodes or other embedded radio products. The reviewed product data indicates that the product data references an operating frequency range of 300 to 450 MHZ, the modulation or band reference includes UHF, the package reference is 16-LSSOP (0.154", 3.90mm Width). Microchip RF transmitter parts are often reviewed for remote keyless entry, RFID, ASK/FSK telemetry and embedded wireless control applications where the exact ordering suffix and package are important. Buyers should verify the full datasheet, output-power setting, data interface, reference clock, antenna matching network, package drawing, marking and ordering suffix before production use or replacement approval.
