1. Define “noise temperature” and “noise figure”. 2. An amplifier consists of a preamp and a power amplifier; which component should have a smaller noise figure and why. 3. A circuit for a single-pole double-throw rf switches of shunt connection is shown Explain how the switch functions and why a quarter wavelength distance in the connection of the diode is needed. 4. Draw an open ckt single stub 5. Draw a Block diagram of a transistor amplifier 6. What are the matching circuits in the amplifier for? 7. What are the design considerations? 8. Why we don’t always choose maximum gain design 9. What are the coordinates of a smith chart and what is the physical domain of the smith chart? 10. How to improve the bandwidth of an amplifier, what is the tradeoff?
