• Description: 12.5khz Channel 12.5khz Channel Vhf High Power Tx
• Manufacturer: Radiometrix Ltd

Functional description
The ENT1 transmitter consists of a frequency modulated Voltage Controlled Temperature Controlled
Crystal Oscillator (VCTCXO) feeding a frequency multiplier with two stage amplifier and RF filter.
Final Power Amplifier stage is factory pre-set to appropriate band power level. Operation can be
controlled by the EN (Enable) line, the transmitter achieving full RF output typically within 7ms of this
line being pulled high. The RF output is filtered to ensure compliance with the appropriate radio
regulations and fed to the 50 antenna pin.
