• Manufacturer Part Number: RX1-151.300-10
• Description: VHF Narrow Band FM High Power TX
• Manufacturer: RADIOMETRIX [Radiometrix Ltd]

Functional description
The TX1H transmitter consists of a frequency modulated Voltage Controlled Crystal Oscillator (VCXO)
feeding a frequency doubler 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 5ms 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.
