Sine oscillator at extremely high frequencies

Let's break down you problem a little bit: We start at 50 GHz. 50 GHz is already an extreme frequency to work at. However, it is possible and there is measurement equipment commercially available to ...

Sine oscillator at extremely high frequencies

You're still way off in your technological estimate of what's doable. At 50 GHz, a 10 pF load is pretty much impossible to drive: |X|=|1/(j2πfC)|, for f=5×10¹⁰ Hz and C=1/10¹⁰ F, is |X|=1/31.4 Ω. At 2 ...

Sine oscillator at extremely high frequencies

For the frequency range you speak of, we don't really have good solid dielectrics. So you'll need waveguides and related hardware just to get the output of the oscillator to wherever the load is. I ...

Sine oscillator at extremely high frequencies

The frequency classes you are interested in are SHF and EHF and range from 3GHz to 300GHz. To create something that works in such frequency bands, new knowledge such as microwave engineering with ...

Sine oscillator at extremely high frequencies

One cannot build such an oscillator. You need different technologies to find something that electronically oscillates at 50 GHz, which is still RF, possible to work with in semiconductor electronics, ...

4 MHz RF-receiver not working

I'm assuming that an input signal voltage source, substitutes for an antenna signal... The signal source impedance of a voltage source is very low, whereas the tank resonator of L1, C1 requires a ...

Intuitive explanation of open stub behaviour

For the shorted stub, consider a transmision line fed with opposite signals from impedance matched sources at each end. what is the signal amplitude at the mid-point? what signal do the sources see? ...
