Hello,
I'm using a microstrip quarter wave transformer with an open end connected to a short stub(part of impedance matching for a transistor).
As far as I know a wider microstrip(smaller Z0) for the transformer would result in better bandwidth. However I cannot understand why!
Can you help...
Re: Problems with microstrip Broadband and selective amplifi
Hi ge,
I think the stubs are off by half of the width of the strip line (~1.4mm) because I start measuring their length form the top of the line, not from the middle.
However today I'm going to test a new board with the stubs...
Hello,
I'm doing a university project and it is my first time to work on amplifiers (or any hardware at all) and I have run at some problem I cannot solve.
My assignment is to build a broadband amplifier, using a gain block circuit and a selective amplifier using a transistor.
I designed the...
