Which transistor configuration has the best high frequency response and also has a low input impedance that approximates the 50 ? rf-circuitry antennas?
A) Common-base
B) Common-emitter
C) Common-collector
D) Base follower

Question

Quizplus · Accepted Answer

The common-base configuration has the best high-frequency response due to its low input capacitance and also exhibits a low input impedance, which can be matched to the 50Ω impedance typically found in RF circuitry and antennas.
