The SR range of receivers are designed to be low-risk, cost-effective building-block modules for high-volume OEM applications requiring radio connection, including use in the 868 to 870MHz pan-European band.

Ideally suited for use in today’s crowded radio telemetry bands, these resilient modules exceed the minimum requirements defined in EN 300 220. The modules are intended for use with the matching ST Range transmitters (see datasheet 1893 2049) for short- and medium-range applications.

With careful system engineering this range can extend to 2km or further.

The receiver modules benefit from excellent sensitivity figures, low current consumption and have both squelch and RSSI facilities.

Frequency control is achieved using modern low-noise PLL synthesiser techniques with non-volatile storage of frequency data allowing serial and parallel frequency selection.

The modules are housed in small lightweight screened enclosures with mounting pins for direct insertion into a customer’s hardware. This electrical screening ensures a family of products complying with current EMC regulations.
