VO3280C/00
Voltage Controlled Oscillator
Features
•Low phase noise
•Excellent pushing and pulling
•Low spurious
•Hermetic thin film/MMIC technology
•Individual recorded data available for each unit
•Very small in size
Description
These new ultra wide band voltage controlled oscillators features an improved integrated voltage regulator
making them even more resistant to external power variations. By using the latest MMIC technology it has
been possible to design a much smaller unit and also enhance uniform performance in serial production.
The oscillator series from S- to P-band covers from 3 to 20 GHz in only four units! The oscillators are all fundamental frequency versions and all have built-in regulators, buffer amplifiers and output filters. All oscillators
are available as drop in or in a SMA house for EMI protection.
The temperature range can easily be extended to cover -40°C to +85°C. However, the standard units are
tested and specified to cover a temperature range of 0°C to 60°C.
Applications
•Microwave instruments
•Sensors
•Radar equipment
•Microwave communication equipment
•ECM (Electronic counter measure)
