Transmitter/receiver handles long ranges

The GT2D is suited to applications requiring a high-integrity wireless connection or where multiple wireless connections are required at the same time.

MK Consultants has released a low-power transmitter and receiver that delivers long-range performance for miniature narrow band FM modules.

The GT2D series operates on the Pan European license-free frequency band of 433 to 434MHz with a power output of 10mW and is available with five individual spot frequencies.

The modules are particularly suited to applications requiring a high-integrity wireless connection and applications where multiple wireless connections are required at the same time.

The small size and low power requirements of the GT2D make it suitable for use in the growing number of portable electronics products that require reliable, long-range, wireless communications capability.

The new module is able to work effectively over ranges of several kilometres in long-range switching and telemetry applications such as wireless security, remote controls, paging systems and asset tracking.

The transmitter is housed in a fully shielded SIL package measuring 32 x 11 x 4mm and is able to operate from 2.3 to 10V DC.

Due to their high RF sensitivity, GR2 receiver modules are able to operate over long ranges complementing the performance of the GT2D transmitters.

A switchable data rate filter gives either 2400 baud with -120dBm sensitivity, or 9600 baud with -114dBm sensitivity.

The receivers are housed in fully shielded SIL packages measuring 48 x 17 x 5mm and feature analogue, digital and true RSSI outputs.

Supply voltage can range from 2.7 to 10V.

Both the GT2D and the GR2 have an operating temperature range of -10 to +55C and are EN 300-220 compliant.
