Local Oscillator / multipliers

PLL controlled Local Oscillators

Using a common PLL locked VCO as base frequency for three Ham bands. VCO is a Mini-circuits JTOS-3000P, 2200 - 2600 MHz turning range 0 to 5 volts.

IF frequency

Turning range from FMTV Modulator 1175 MHz to 1325 MHz

9 cm band

3.5 GHz Mixer diode pair HSMS-2822

VCO frequency + IF frequency = RF frequency

I.e. 2.25 GHz + 1.2 GHz = 3.45 GHz

5 cm band

5.7 GHz Mixer diode pair HSMS-2822

VCO frequency x 2 + IF frequency = RF frequency

I.e. 2.25 GHz x 2 + 1.2 GHz = 5.7 GHz

3 cm band

10 GHz Mixer diode pair HSMS-8202

VCO frequency x 2 x 2 + IF frequency = RF frequency

I.e. 2.25 GHz x 2 x 2 + 1.2 GHz = 10.2 GHz
