It seems like all of them refer to the same frequency range, but what about the differences?
Plz help, thanks!
I saw many papers on PA and filters, so I guess that they are more difficult to design than other modules in a transceiver.
For example, there are many papers on PA linearization, and novel filters to improve the passband's shape. There are also many professors specialized in PA and filters in...
For general wireless communication, power amplifiers may be the design bottleneck, because the linearity and the efficiency are hard to balance, right?
For satellite communication, filters may be the design bottleneck, because the requirements are much higher than that of general wireless...
The problem is, that a dielectric resonator is shielded by a PEC cavity, and thus eigenmode simulation in Ansoft HFSS will acquire resonant modes of both the metal cavity and the dielectric resonator.
If the size of the cavity is reduced to increase the frequency of the lowest mode of the...
dielectric resonator
I know what you mean, but I am required to include some simulation results in my report. And the principle of the oscillator is self-oscillation induced by parallel positive feeback, so stimulation may not be available in my report. The experiment of the oscillator has...
dielectric resonator oscillator
Most RF transistors need input matching and output matching(conjugate matching) to achieve maximal gain. However, the PARALLEL FEEDBACK DIELECTRIC RESONATOR OSCILLATORS(DRO) do not need the matching.
Here comes the problem: if there is no matching, the loop gain...
