Tristron- a frequency multiplier
International Conference on Actual Problems of Electron Devices Engineering, 2004. APEDE 2004., 2005Investigation of harmonics of a current in tristron is executed by numerical modelling. It is shown, that tristron can be an effective frequency multiplier. Designing of tristron on frequency of 2450 MHz with electronic efficiency of 60 percent is executed.

Magnetic frequency multipliers
Electrical Engineering, 1954WITH the availability of high-quality magnetic core materials, it has become possible to develop very efficient magnetic frequency multipliers. The advance of the electronic arts in the development of computers and precise control systems has created the immediate need for frequency multipliers which can produce exact multiplication of frequencies in ...

Electrical Engineering, 1962
A novel arrangement of n transformers delivers power at n times the line frequency. Ratings compare with transformers of the same weight. Waveform and voltage regulation are excellent. An experimental 7X unit with 60-cycle input gave 3.6 kw of 420-cycle output at approximately 90% efficiency. An additional 5X stage gave 2,100 cycles.

IEE-IERE Proceedings - India, 1971
Design details and perfomance of a 2–4 GHz doubler using a disk seal triode is presented. The tube is mounted on the central conductor of a 3λ/4 resonator at the anode. The 2GHz input is applied, through a capacity probe, to another 3λ/4 resonator tuning the cathode. The resonators are built around the tube and are tunable over a small range.

A Low-Power Clock Frequency Multiplier
2006 IEEE International Symposium on Circuits and Systems, 2006A low-power output feedback controlled frequency multiplier is proposed for delay locked loop (DLL) based clock synthesizers. It uses N voltage controlled delay lines (VCDL) to multiply the input clock frequency by a factor of N/2. This frequency multiplier is less susceptible to jitter-accumulation.

A frequency multiplier for reference frequency in frequency synthesizer systems
Analog Integrated Circuits and Signal Processing, 2017A low jitter frequency multiplier, which requires less power, area, and design complexity than reference multiplying PLL or DLL circuits can be used to generate the reference frequency for a low phase noise frequency synthesizer. This paper proposes a mixed signal solution based on the fact that the average DC value of a signal is proportional to its ...

A 45GHz SiGe active frequency multiplier
2002 IEEE International Solid-State Circuits Conference. Digest of Technical Papers (Cat. No.02CH37315), 2003A frequency quadrupler for frequencies up to 45 GHz uses a pre-production 0.4 /spl mu/m SiGe bipolar technology. Gain is achieved at -15 dBm input power between 24 and 45 GHz with maximum of 7.3 dB at 44 GHz. The circuit draws 84 mA from a single 5 V supply.

Frequency multiplier with a feedback
Measurement Techniques, 1964A multiplier with a feedback has the unique combination of the following properties: a wide range of multiplied frequencies (10:1 and wider); a large and easily variable scaling factor; it is independent of the input signal voltage shape or amplitude; it can operate with a variable input frequency; it is insensitive to stray frequency modulation of the
