Voltage Controlled Oscillators of VCOM-X/CF/BW/P series

Voltage controlled oscillator of VCOM-X/CF/BW/P series was originally designed for purposes of EPR spectroscopy and plasma diagnostics. Now this VCO is included to ELVA-1 Product Catalog as state-of-the-art test and measurement equipment for various applications.

VCO Features

• High output power
• Electrical Frequency control
• High power and frequency stability
• Control of Output power level
• Stable spectrum
• Long life time

VCO Applications

• Mm-wave source of high power
• EPR spectrometer bridge
• Plasma diagnostics
• FMCW radar module
• Instruments and test equipment

This VCO provides electromagnetic energy within some range around of central frequency with high output power. Original design uses low frequency stable voltage controlled oscillator and frequency multiplier. To increase output power an IMPATT mm-wave power amplifier can be used. Max value of output power level depends on frequency range requested. It can be 200 mW at 94 GHz and 50 mW at 140 GHz.

Output power and frequency are controlled by means of external DC or pulse voltages.

The VCOM-X/CF/BW/P oscillator can be supplied with power supply which fed only 220 VAC. The oscillator can have an option for remote control.

Reliable work of VCOM-X/CF/BW/P oscillators allows to use it in scientific experiments which last for long time, for example, few weeks or even few months.

There are three basic models of the VCOM-X/CF/BW/P oscillators in ELVA-1 product line. Custom designed VCOM models can be produced by a special order.
