I want to know about input and output impedance of amplifiers with examples

 

I have a single transistor amp, the BFR92A in SOT23 package, in CE setup, with 10uH chokes used to bias attached 5mm from base (0.8V) and collector (9.8V) with 5mm leads, with input reflection coefficient of 0.331374 @ -169.024deg and output reflection coefficient of 0.570281 @ -24.605deg, all at 1GHz. Find the input and output impedance in a 50-ohm system, and stub lengths to match the input and output using two double-stub networks (1/8-wavelength in between stubs). DC, amp configuration, signal frequency, and package details are not required for the solution, just the reflection coefficients.
