Project description
Offering remote earnings. It is necessary to develop schematic diagrams of the Power Amplifier, antennas consistent devices, modulator, frequency synthesizer.
Required characteristics:
1. Frequency synthesizer:
Formation of a frequency grid from 3 to 30 MHz with a step of 1 kHz, frequency stability of 10^-6. Reconfiguring the frequency from the keyboard
2. Power amplifier: signal amplification up to 1W
3.Modulator of telegraph signal: modulation is carried out using a telegraph key, signal bandwidth 300Hz
4. Antenna-matching device for a pin antenna of small size (20-25 cm antenna size)
