VHF radio transmitter / UHF

The ST range of transmitters 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.They are intended for use with the matching SR Range receivers (see datasheet 1893 2048).

Ideally suited for use in todays crowded radio telemetry bands, these resilient modules exceed the minimum requirements defined in EN 300 220.

The VHF and UHF transmitter modules deliver up to 100mW RF output power.The 868MHz version is reduced to 25mW to match the recommended plan for this band. Such power levels are more than adequate for short- and medium-range applications.

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

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 customers hardware. This electrical screening ensures a family of products complying with current EMC regulations.
