MK Consultants has introduced the FM transmitter GT2HP-UHF. The module operates at the UK license-free frequency of 458.85MHz and has a power output of 250mW. It can be paired with the MK Consultants GR2 receiver. Housed in a fully shielded 31mm x 19mm x 4mm miniature SIL package, the GT2HP-UHF has a common Genesis footprint, this allows the module to be  incorporated into existing designs. The transmitter uses narrow band crystal technology and can achieve data rates of up to 9600 Bits/S.

The module requires a nominal DC supply of 5V and has a channel spacing of 25KHz. Although initially available with an operating frequency of 458.85MHz for the UK market, the GT2HP-UHF can be supplied with other frequencies if required.

GR2 receiver modules are able to operate over long ranges complementing the performance of the GT2HP-UHF transmitter. A switchable data rate filter gives either 2400 baud with –119dBm sensitivity, or 9600 baud with –114dBm sensitivity. The receivers are housed in fully shielded SIL packages measuring 48mm x 17mm x 5mm and feature analogue, digital and true RSSI outputs. Supply voltage can range from 2.7V to 10V. Both the GT2HP-UHF and the GR2 have an operating temperature range of –10ºC to +55ºC and are EN 300-220-2 compliant.
