Since the QBH-2001 is a single ended low noise amplifier, it is important the source impedance of the circuit connected to the QBH2001 RF input port is as close to 50 ohms as possible (source return loss better than 20 dB). Keeping good 50 ohm source impedance is important because good noise figure of the amplifier will be affected if source impedance degrades. Another important factor affecting performance is input circuit losses. A good microwave transmission medium should be chosen and T1 transmission line length should be kept as short as possible to maintain lowest possible noise figure. C1 should be a high Q microwave capacitor to minimize resistive losses.
