SI4032-B1-FMR

Product Overview

SI4032-B1-FMR is a FSK/GFSK RF transmitter IC from Silicon Labs, 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 240 to 930 MHZ, the modulation or band reference includes FSK, the package reference is 20-VFQFN Exposed Pad. Silicon Labs transmitter parts are frequently used in configurable ISM-band wireless designs, remote-control products, sensor nodes and proprietary low-power RF systems. 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.
