Hi,
I am confused about the format of input and output impedance of RF transistors. For some devices impedance are given in series form and in parallel form for other devices. Some data sheets do not mention. Why series to parallel or parallel to series transformation is required.
I am using pd85004 ldmos for amplifier. When its model is simulated in ads using LSSP simulation, which impedance format parallel or series it gives?
