Webmatching. Matching networks normally are low-pass or pseudo low-pass filters. If QlN is high, it can be necessary to use band-pass filter type matching networks and to allow insertion losses. But broadband matching is still possible. This will be discussed later. 2.2 OUTPUT IMPEDANCE The output impedance of the RF-power transistors, as WebFeb 26, 2005 · anatech. My experience shows that, in order of importance, the pairs must be matched (NPN to NPN, PNP to PNP). Then, each pair should be matched to the other. There is a difference if you include the last step.
