DEVICE FOR ELECTRONIC TUNING OF MILLIMETER-WAVE FREQUENCY

Purpose
Resonant systems fast frequency tuning in ranges from superhigh frequencies to tremendously high frequencies (THF).
Can be used in filters, frequency counters and during measurement of matter parameters and humidity of dielectric and composite materials.

Characteristics

Frequency range 0,6 -- 180 Hz
Frequency tuning range from carrier 1 -- 15%
Frequency tuning speed > 1 GHz/us
Manufactured from thermostable materials  
Lightweight and compact  
Parasite low-frequency resonances are completely eliminated  
MICROWAVE RECEIVER-TRANSMITTER FOR WIRELESS COMMUNICATION

Application
Belongs to new information technologies, that are aimed to fast transmission of large volumes of digital information to long distances. Can be used for high speed transmission of analog and digital data (videoconferencing service, telephony with distant correspondents, mobile communication system for management of traffic flow, cell phone systems etc.). The selection of working frequencies for receiving-transmission facilates high secrecy and hindrance protection of system operation (military communication systems, radio relay lines).

Test bench for measurements of electrophysical parameters of nanomaterials in microwave frequency range

Application
Study of nanomaterials in microwave frequency range

Specifications
Composite nanomaterials have variable material parameters. Experimental measurement of electrophysical parameters of these materials in frequency range 2-78 GHz is the most important problem in modetn radio-frequecy engineering and electronics. Physical concepts of measuring of characteristics of artificial composite materials were developed in resonators with high Q-factor: dielectric losses (complex, real and imaginary components of permittivity)

Components of test bench:

- Microwave generator
- Gate
- Directed y-junction
- detector head
- electronic counting frequency meter
- Resonator with high Q-value with sparse spectrum of eigenfrequencies.
