                        provide a high return loss at all frequencies. In other words, matching the
                        transistor at high frequencies will supply more gain at these frequencies,
                        while mismatching at the lower end of the spectrum will decrease the gain at
                        these frequencies because of mismatch losses. However, stability is always of
                        prime importance; since we now have various impedance mismatches across a
                        wide bandpass—and also at frequencies both below and above the bandwidth
