ELVA-1 Cavity Stabilized IMPATT Oscillators 26-150 GHz
See full specification tab below or
ELVA-1 presents mm-wave oscillators of CIDO-XX family operating at fixed frequency. The CIDO-XX are cavity-stabilized IMPATT diode oscillators. They provide high frequency stability and low phase noise capability. They combine the extended frequency range and high output power of IMPATT oscillators with stability and phase nose capabilities provided by cavity-stabilized Gunn oscillators. The CIDO-XX sources are available in 8 waveguide bands covering 26 to 150 GHz. The CIDO-XX source consist of a waveguide cavity IMPATT oscillator which is coupled to a high Q, high order mode cylindrical cavity. The cylindrical cavity is made of Invar to improve the frequency stability over a broad temperature range. Operating temperature range is -50 to +80 ºC. Low pass EMI filter and current stabilizer included for reliable, trouble-free operation. The device supplied with an integral isolator.
Standard CIDO-XX models are supplied mounted on a finned heat sink. These oscillators can maintain their operating frequency within few megahertz over the normal operating temperature range without a temperature controller or heater. An optional built-in temperature controlled heater can be supplied to maintain the oscillator within a narrow operating temperature range. The frequency can be held in a much narrower range. Custom configurations and performance characteristics different from standard models are available.
