You are considering using a Minicircuits ERA-51sm amplifier in a design for a low noise amplifier at 2 GHz with a 50 ? input impedance.
1. What is the equivalent series input resistance for this amplifier?
2. What are the stability factors (K, ?) for this amplifier at 2 and 3 GHz?
Find the noise temperature for a Cal-Amp C-Band 140105-1 low noise block down converters (LNB) for satellite TV. What is their equivalent series input resistance, and what implications does this have for the circuit design?
