The TX3H-869.5-15 from Radiometrix, is an FM transmitter module achieving a power output of 450mW at 869.5MHz. It is fully pin-compatible with the company's established range of SIL TX modules and is a drop-in UHF replacement for the TX1H VHF product, having near identical dimensions of only 45x17x6mm.
TX3H is an excellent 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 new RX3G, depending on the type of antenna used and the environment.
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.
