NOTES:

1. Please use L1 to stabilize amplifier. This element pull input impedance down at low

frequency region (up to 400MHz).

2. Please use chip inductor which has low resistance at input circuit. (A low resistance inductor

of 1608 size (1.6mm x 0.8mm) is used in the circuit example above.) Because any losses at

input circuit cause NF degradation.

3. The capacitor C3 is a bypass capacitor connected with self-biasing resistor. The small signal

gain can be controlled by this capacitor. (Gain=18.5dB @ C3=30pF)
