VHF/UHF radio transmitter
ST500
Wood & Douglas
Ideally suited for use in today’s 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 bandplan 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. 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.
