Description

 

         ELVA–1 series IMPATT Active Frequency Multipliers IAFM are really unique devices providing an outstanding performance in terms of high efficiency and high output power. Available in multiplication factor up to 25 inone device they cover the output frequency range of 20 to 180 GHz using centimeter-wave range source. They are capable of handing very high input power without damage. Different IAFM’s would operate with the same centimeter-wave range pumping source. For example, on the picture above you can see the pumping source (20mW, 7.2775 GHz) and three different multipliers: IAFM-28 (5th harmonic, 36.3875 GHz), IAFM-15 (8th harmonic, 58.2200 GHz) and IAFM-10 (13th harmonic, 94.6075 GHz). The phase and amplitude stability of the output signal defined by the quality of the pumping source. It is possible to achieve Hz resolution on 150 GHz using state-of-the-art synthesized cm-wave source. The frequency multipliers are designed as a module, that consists of centimeter-wave high power preamplifier, a multiplier itself, band-pass filter and isolator. Current stabilizer included for reliable, trouble-free operation. The band-pass filter rejects the side band noise of the source on about -50 dB. That allows to use the device as low noise solid state LO, if intermediate frequency is higher then the frequency of rejection. The input of multiplier is a coaxial connector, and the output is a waveguide flange
