UHF-FM Synthesized-Power-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 ETS 300086 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.
