Please, look at http://www.rfcomp.com/hd24223.aspx (the spec file is downloadable in this page). This is a microwave amplifier, and I have several questions.
1) What is "noise figure" ?
2) What is P1DB ?
3) What is IP3 ?
4) What is VSWR ?
5) Does this power amplifier works like an OpAmp, that is, does it amplify any signal linearly ? is there an input offset like transistors, or is it able to amplify extremely weak signals ?
6) How did they make this amplifier ? the most skilled radio Ham can only design a circuit to amplify up to 3 GH, and it is well known that all diodes and transistors do not switch so fast, every resistance and capacitance have small (but extremely disturbing at these frequencies) parasitic impedances. So, how do they that ? thx.
