Compact VHF transmitter produces 300 mW for reliable data links

15 November 2006 Telecoms, Datacoms, Wireless, IoT

The HX1 from Radiometrix is a narrow-band VHF radio transmitter module designed for use in a variety of data transfer applications.

When used in conjunction with the matching RX1, BiM1R or CVR1 receiver modules, a one-way radio data link can be created that is capable of spanning distances of over 10 km (if a suitable data rate and antenna set up are employed).

This radio module effectively offers the popular Radiometrix BiM1T transmitter in a TX1 pin-out, with only slightly-enlarged proportions to accommodate the extra power amplifier circuit (full dimensions; 43 x 15 x 5 mm). According to the manufacturer, it has substantially more power than devices normally associated with this footprint size, and so gives design engineers the raw materials to create a wireless solution more capable of satisfying their demands.

It produces a 300 mW (24,7 dBm) RF output, supporting a maximum data rate of 3 Kbps, and has a frequency placed within the 169 MHz European licence-exempt band, although it is available with all transmit frequencies in the 120 and 180 MHz band. The device has a modulation bandwidth of 0-3 kHz at -3 dB. It runs off a standard 5 V regulated supply, and typically draws a current of no more than 140 mA.

With low power consumption and long range, this transmitter is highly-suitable for use in asset tracking or non-contact meter reading systems, as well as paging devices, social alarms for the elderly or disabled, datalogging, and high-end security/fire alarms systems. This unit is fully-compliant with EN300-220.
