The crystal-based PLL controlled FM transmitter operates off an input voltage of between 2.2 and 4V (allowing it to be used in portable, battery-powered system designs) and delivers nominally +0dBm at 7mA. The transmitter module is approved to the EN 300 220-3 and EN 301 489 standards. Internal filtering helps to ensure EMC levels are kept low by minimising spurious radiation. Key applications for this module include car/building security systems, EPOS monitoring, inventory tracking, remote industrial process control, and computer networking.
UHF FM Transmitter Module from Radiometrix
The TX2S, from London-based wireless module manufacturer Radiometrix, is a miniature PCB mounting UHF radio transmitter for the 433.92MHz (UK) or 434.42MHz (European) radio bands. Contained within a compact package, measuring just 20x10x2 mm, it allows design engineers to create a simple data link (either with a node-to-node, or multi-node architecture) which is capable of supporting rates of up to 40kbits/s at distances of as much as 75m in-building and 300m across open ground.
