DTX-99U Radio Transmitter

The DTX-99U Radio Transmitter integrates a high-power RF section and an internal Output&Reverse RF Power measurment circutry, allowing for on-site optimal antenna matching. The on-board microprocessor is used to set the transmission frequency and to measure transmission parameters.
This very small (100x55x26 mm.) and high-power unit is ideal for externally modulated Alarm/Telemetry data transmisiion.
