TRF4400PWRG4

Product Overview

TRF4400PWRG4 is a FSK/GFSK RF transmitter IC from Texas Instruments, 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 around 433 MHZ; confirm operating bandwidth in the datasheet, the modulation or band reference includes FSK, FM, the package reference is 24-TSSOP (0.173", 4.40mm Width). Texas Instruments RF transmitter ICs are commonly evaluated for sub-GHz wireless links, low-power telemetry, remote controls and ISM-band equipment. 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.
