CIRCUIT POWER DIVIDERS/COMBINERS 

We are suggesting the circuit power combiners/dividers (PD/PC) in hybrid-integrated implementation.

At customer offer all modification of products can be delivered as printed circuit board and also as case type wit SMA-F connectors.

It is used in:

—  power dividers/combiners;

—  balanced circuits of power amplifiers;

—  balanced mixers;

—  mixers with image channel suppression;

—  phase shifters;

—  duplexers;

            —  beam formers.

Various modifications of  device are released

VOLTAGE CONTROLLED OSCILLATORS (VCO)

Oscillators are used in radio devices with frequency tuning.
Have smooth frequency tuning  in a range.
The structure is sealed.


Six types of oscillators are produced: 

 

  • VCO-70; VCO-100; VCO-500;

VCO-S-100; VCO-S-200; VCO-S-400

 

 

Frequency range:

VCO-70 65…75 MHz
VCO-100 88…108 MHz
VCO-500 430…520 MHz
VCO-S-100 30…110 MHz
VCO-S-200 30…110 MHz
VCO-S-400 220…400 MHz

The  VCO-S models contains internal synthesizer, by which the frequency with a step up to 5 kHz is set.
For synthesizer operation the external reference oscillator with frequency 1…20 MHz is  used.

Output signal level 200 mV
Harmonics suppression 20 dB
