The TX3H-869.5-15 from Radiometrix is an FM transmitter module that achieves a power output of 450mW at 869.5MHz.

It is fully pin compatible with the company's range of SIL TX modules and is a drop-in UHF replacement for the TX1H VHF product, having near identical dimensions of 45mm x 17mm x 6mm.

TX3H is a suitable choice for the designer of a licence-exempt wireless data application where the size of antenna is restricted yet a range in kilometres is also specified.

The module can support data rates of up to 15kbits/s and has a potential range of 5km or more when paired with Radiometrix receivers such as the RX3G, depending on the type of antenna used and the environment.

The module requires a 5V regulated supply capable of delivering 350mA during transmissions.

TX3H-869.5-15 operates within the European 869.40-869.65MHz sub-band allocation, although custom frequencies may be accommodated on request.

It has been designed to comply with EN301 489 (EMC) and EN300 220 (SRD) radio standards.

This module can be employed in a large number of end applications, such as asset tracking systems, meter readers, industrial telemetry/telecommand equipment, data loggers, in-building environmental monitoring/control systems, social alarms, high-end security/fire alarms, and vehicle data up/download.
