Design of FET frequency multipliers and harmonic oscillators by Edmar Camargo

By Edmar Camargo

Introducing the applying of box influence Transistors (FET) as frequency multipliers and harmonic oscillators, this article places emphasis on nonlinear strategies, and incorporates a minimum quantity of arithmetic and a mixture of conception and experimentation. It goals to aid microwave and millimeter-wave engineers understand the elemental ideas and layout principles of frequency multipliers and harmonic oscillators. The textual content specializes in the thoughts required to generate harmonics and emphasizes circuits. It explores the layout of slim and bandwidth doublers and triplers - either single-ended and balanced configuration. It additionally explains the organization among oscillator conception and frequency multiplier thought in designing harmonic turbines. the $64000 concerns whilst utilizing MIC or MMIC applied sciences are mentioned to assist designers decide upon the easiest procedure for a specific circuit.

Sample text

It is seen that for Al the largest concentration of neutral particles was obtained for 30 ns delay for both heating pulses, while for Cu better results were found for 40 ns delay. One should note that, at given HHG conditions (driving pulse is not ultrashort, plasma is not very dense, no resonant absorption is present), the plasma concentration influences the HHG yield mainly in two ways. It increases the number of particles participating in HHG, and thus HHG intensity grows with the increase of the concentration, and further it increases the number of the free electrons, which influence HHG efficiency in a rather complicated way.

We analyze the reported results of harmonic generation from mono- and nanoparticle- containing plasma plumes, compare the harmonic yields from Zn, Cu, and brass alloy to address the issue of interference of harmonic generation from species of different origin, and finally compare the HHG efficiencies from gaseous (argon) and plasma (carbon) media at comparable conditions [117]. A 1 kHz repetition rate chirped pulse amplification Ti:sapphire laser was used as the laser driving source. The scheme of HHG was similar to the one described in Sect.

The position of the focus relative to the plume was chosen to maximize the harmonic output. HHG experiments were also performed using the femtosecond pulse with 40 fs duration as ablating pulse. 6 mJ for the heating and the harmonic driving pulses (Fig. 10a). The harmonic emission was analyzed using an XUV spectrometer consisting of a flat field grating and MCP detector coupled to a phosphor screen. The images of harmonics were captured using a cooled CCD camera. The XUV spectrometer allowed the registration of the 11th to 23rd harmonics of 800 nm radiation.
