AS3977B-BQFS

Product Overview

AS3977B-BQFS is a FSK/GFSK RF transmitter IC from ams-OSRAM USA INC., 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 928 MHZ, the modulation or band reference includes FSK, the package reference is 16-VQFN Exposed Pad. ams OSRAM transmitter devices are often evaluated for low-power wireless, sensor and embedded RF transmitter designs where the exact carrier band and package variant should be verified. 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.
