Method and apparatus for quadriphase-shift-key and linear phase modulation [PDF]

open access: yes, 1980
A submultiple of an S-band transmitter output frequency was divided equally between a linear phase modulation branch and a QPSK modulation branch. The linear modulation branch includes a multiplier to increase the carrier frequency to a level which, when

Microstrip doubler microwave with non-traditional implementation

open access: yesTekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2019
Frequency multipliers are used in electronic devices to generate spectrally pure sinusoidal signals in the frequency range from a few to tens of GHz. The multipliers are used to multiply the frequency of highly stable but more low-frequency devices with ...

Low jitter frequency multiplier [PDF]

open access: yes, 2019
182 p. This thesis I explore the research in the area of low jitter frequency multipliers before proposing a novel new design for such a multiplier. The thesis begins with an analysis of the random and deterministic noise arising from conventional phaselocked loop (PLL) and delay-locked loop (DLL) based frequency multipliers.

High-performance aperiodic frequency multiplying

open access: yesElectronics Letters, 1979
A circuit is described that multiplies the frequency of a sinusoidal signal by a factor of 3 (and even of 5) yet maintains the input/output amplitude ratio strictly constant over a large range. A special translinear configuration was designed and used, together with commercially available analogue multipliers, to build the circuit.

Impact of Ultra-Wideband Electromagnetic Interference on the Performance of a Passive Frequency Doubler

open access: yesIEEE Access
This article investigates the impact of ultra-wideband (UWB) electromagnetic interference (EMI) on the performance of a passive frequency doubler. The doubler, fabricated using $0.5~\mu $ m GaAs Schottky technology, was characterized under various UWB ...

Holder Continuous Solutions of Active Scalar Equations [PDF]

open access: yes, 2014
We consider active scalar equations $\partial_t \theta + \nabla \cdot (u \, \theta) = 0$, where $u = T[\theta]$ is a divergence-free velocity field, and $T$ is a Fourier multiplier operator with symbol $m$.
