There are some amplifiers that must have low input impedance,high output impedance and operate at high frequencies, the common grid amplifier is the best choice. (Example: for loading high Q resonant circuit).
You can use common grid/gate/base amplifier up to ft of active component for making...
You can make with one tube - resonant circuit and then place saturation circuit.
Is not relaxation oscillator, but it works.
(keep in mind that resonant circuit plays the role of transformer in amplitude tranbsformation ratio)
Best regards.
Hi,
y have also ubunto, y completely removed windows. If you want to use windows software you can use wine / xine / vmware. Personaly I use wine / vmware
Hi,
I think you can measure the nonlinearity by the classic two tone test or triple beat method. First I start with pure tone and superposed DC Bias for magnetization curve and extracting the tranformer parameters.
Because two or more tone test is difficult if not high isolation (the sum of...

if is for reception a small binocular transformer made by 8:5 turns ratio can be done good results. Since 8/5 = 1.6 and (1.6)^2 = 2.56 close to desired ratio.
Try also a quarter wave transformer made by microstrip. Multisection transformer gives you broadband...
Hi,
I'm designing very high power amplifier for wireless communications (2 kW), in my case efficiency/linearity is the bottleneck.
For satellite communications I think that the bottleneck is LNA, but also good efficiency is important, and good response to extreme enviromental factors such as...
