NOTES:
1. Please use L1 to stabilize amplifier. This element pull input impedance down at low
2. Please use chip inductor which has low resistance at input circuit. (A low resistance inductor
3. The capacitor C3 is a bypass capacitor connected with self-biasing resistor. The small signal
frequency region (up to 400MHz).
of 1608 size (1.6mm x 0.8mm) is used in the circuit example above.) Because any losses at
input circuit cause NF degradation.
gain can be controlled by this capacitor. (Gain=18.5dB @ C3=30pF)
