K-Band Frequency Synthesizer with Subharmonic Signal Generation and LTCC Frequency Tripler
2008 38th European Microwave Conference, 2008A subsystem implementation study of a fractional-N frequency synthesizer for K-band satellite communications is presented. The architecture is based on a subharmonic frequency generation implemented with commercially available voltage-controlled oscillator, phase-locked loop chip and a custom designed frequency tripler implemented in low temperature co-

Two 81-96 GHz Active Frequency Triplers MMIC
Applied Mechanics and Materials, 2015Two 81-96 GHz frequency triplers, one balanced and one single device, are implemented using a 0.10 μm GaAs pHEMT process. The EM simulation results show that the triplers perform a best conversion gain of -6.8 and -4.7 dB for the balanced and the single device, respectively.

A stability ensuring design approach for frequency triplers
2001 IEEE MTT-S International Microwave Sympsoium Digest (Cat. No.01CH37157), 2002A novel design procedure for frequency triplers is presented. After first determining optimum bias conditions for frequency triplication, stable regions of operation are determined. The dependency of output power and conversion gain as functions of terminating stubs at all frequencies is examined. An experimental validation is finally carried out.

The design of a 0.33 THz frequency tripler
2016 IEEE 9th UK-Europe-China Workshop on Millimetre Waves and Terahertz Technologies (UCMMT), 2016In this paper, we use suspended microstrip to design a 0.33 THz fequency tripler, in which a pair of Schottky varactor chips parallel is adopted. Considering the present processing technology, it's easy for the unbalanced structure to provide bias to the diodes without an on-chip capacitor, which is essential to the balanced tripler scheme. The tripler

255 to 330 GHz active frequency tripler MMIC
2012 Workshop on Integrated Nonlinear Microwave and Millimetre-wave Circuits, 2012An active frequency tripler MMIC achieving an output frequency of 330 GHz is presented. With the use of integrated post- amplification the frequency tripler generates an average output power of −0.4 dBm in the output frequency range from 255 to 330 GHz, corresponding to an absolute bandwidth of 75 GHz.

Sinusoidal frequency tripler using fundamental-rejecting feedback
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1995The author presents a sinusoidal frequency tripling circuit which uses an operational transconductance amplifier (OTA) to distort the input signal and generate odd harmonics. By means of a feedback loop that rejects the fundamental of the distorted signal, the circuit produces an output signal whose frequency is three times the input frequency, and can

Improvement of Performance of the Magnetic Frequency Tripler
IEEE Translation Journal on Magnetics in Japan, 1985Numerical analysis was used to obtain the characteristics resulting from connection of a filter to the input of magnetic frequency triplers, which utilize the nonlinear characteristics of magnetic cores to obtain triple-frequency outputs. The magnetization characteristic of the circuit saturation reactor was approximated by two connected straight lines;

A Pure Frequency Tripler based on CVD Graphene
IEEE Electron Device Letters, 2016In this letter, the chemical vapor deposition grown single-layer graphene with micrometer scale graphene flakes interspersed on the surface has been first used to implement field-effect transistors (FETs) for the purpose of frequency tripling. Two Dirac points can be observed in the transfer curves of the designed FETs, which are essential to generate ...

Broadband frequency tripler design at 40–60 GHz
2016 Asia-Pacific Microwave Conference (APMC), 2016This paper describes the design and fabrication of broadband frequency tripler in U-band (40–60 GHz) using anti-parallel beam lead Schottky barrier diodes MGS901 from Aeroflex Metelics. The whole circuit is constructed on suspended stripline technology and mounted in a waveguide block that includes matching elements in the input side.
