Data Link 450 - Specialist Transceiver Brochure

WIRELESS DESIGN DEVELOP DELIVER Data Link 450 Specialist Transceiver > Single-board UHF Radio Modem > Synthesised frequency > Multi-channel capability > EN 300 220 approval > Low current consumption > Low cost > Easy to use – RS232 data in/out > Low-profile package The Data Link 450 transceiver is a miniature high-quality module for data and telemetry transmission in the less-congested rural markets where distance of communication is the most important factor. Combining sensitive receiver circuitry with a matching 500mW RF transmitter section, this module will find use in short-, medium- and long-range applications. Such a power level will deliver a very effective increase in range performance over lower-power wideband devices while balancing the need for battery economy in portable applications. The modules are housed in small lightweight screened enclosures with multi-way connection interface for either cable or direct pcb mounting. This electrical screening ensures full compliance with current EMC regulations. Frequency control is achieved using modern low-noise PLL synthesiser techniques with non-volatile storage of frequency data, allowing serial and parallel frequency selection. To satisfy customers using advanced modulation schemes, special versions of this range are available with extended audio characteristics. Ask Wood & Douglas Sales for details. Designed, manufactured and supported from the UK and benefiting as standard from extensive type approvals, these units provide the OEM with a high-quality, low-cost-of-ownership route into quality radio applications.
