• Behavior of a transistor in power amplifiers is unpredictable at all input signal levels.
• If the power input to an antenna is 100 mW and if the radiated power is measured to be 90 mW, then the efficiency of the antenna is:
• Amplifier efficiency is the ratio of RF output power to DC input power. This parameter determines the performance of an amplifier.
•                        amplifiers are linear circuits, where the transistor is biased to conduct over the entire range of the input signal cycle.
• High gain is not achievable at microwave frequencies using BJT amplifiers because:
• In conventional amplifiers, a flat gain response is achieved at the cost of reduced gain. But this drawback can be overcome by using:
