SX1240ISTRT

Product Overview

SX1240ISTRT is a ISM-band RF transmitter IC from Semtech Corporation, 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 418 / 434 MHZ bands, the modulation or band reference includes ISM, the package reference is 8-SOIC (0.154", 3.90mm Width) Exposed Pad. Semtech transmitter devices are commonly reviewed for ISM-band telemetry, remote-control and low-power wireless data-link designs. 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.
