Title: Transceiver 70TRX-TP

Narrow band 200mW multi channel transceiver 70TRX-TP

The new designed FM power transceiver module 70TRX-TP from HM-Funktechnik is an absolut high end module with internal synthesizer and microcontroller to convert the external 8 bit wide channel information into the serial data protocol for the synthesizer chip. No complicate programming is needed. The module offers 139 channels in the european 70cm ISM frequency range from 433.05 to 434.79 MHz and corresponds to EN 300113 demands.

Upon request it is also available for frequencies within the range from 410 to 510MHz and a switching bandwith of 5 MHz max. The dual conversion system is simply a must for high end applications. The module has a remarkable selectivity, which allows its use in applications where several modules must be operated locally and on adjacent radio channels at the same time.

The excellent RF sensitivity of –116dBm by CCITT weighting allows its use for long distance signal transmissions.

The direct audio signal output doesn`t restrict its use for any kind of coding. Any type of recommendable signal can be used, even direct audio signals, e.g. speech.

The combination with another transceiver-module 70TRX-TP offers the user a perfect radio system with long distance communication at half-duplex. Together with our remote control unit FSM24 you can reach 3300 m and more at free sight.
