T Series - Transceiver Modules Brochure

WIRELESS DESIGN DEVELOP DELIVER T Series FCC part 90 transceivers for radio telemetry two lines if need be > T100: 135 to 200MHz > T200: 200 to 270MHz > T400: 400 to 480MHz > Designed to satisfy North American approvals (FCC, DOC) > Compact size > Synthesised design > Data recovery circuit > RSSI output > 2W RF output (5W option) T Series The T Series modules provide a cost-effective, high-quality radio transceiver to exceed North American and equivalent radio telemetry specifications. Today’s crowded frequency spectrum creates increased potential for both in- and out-of-band interference. This threat places demands on radio module performance. The T Series modules address this challenge by providing synthesised frequency agility in association with good large-signal handling characteristics. These modules offer good receiver sensitivity, 2W or 5W RF output and a wide choice of frequency variants. Interface connections are industry-standard D-type and BNC. The T Series offers on-board channel storage or dynamic external frequency loading, ‘S’ meter output and receiver data recovery circuit. The engineering integration and attention to detail has ensured the T series offers a radio transceiver at a cost-effective price that will out-perform other low-cost imports to the US market.
