פיתוח מעגל signal generator יעיל
1. General:
input: 9-24 vdc (battery)
output: 1-10v ac, sine wave (5% distortion max), 1-50 mhz
the output will be directed to an antenna wih evaluated impedance of 100 ohms.
part of this reuqirement is to measure the ant. imp. and match the circuit to it.
the circuit will be responsible to get the input dc and convert it in a very efficient way to the required ac signal.
Note: minimum efficiency: 80% (if not possible - state the min.eff. available)

2. Controls:
Manual adjustments will be made by potentiometers or other digital/analog buttons:
a. Amplitude - controls the amplitude of the sine wave - Vpp is between 1 to 10v
b. Frequency - 1-50 mhz, min step is 0.1 mhz, better is 0.05 mhz

3. Misc.
LCD display - an advantage, not must.
the circuit must be delivered fully assembled and tested to be fully working (for the supplied antenna circuit), on a PCB, delivered also with all its schematics and a full part list.
