Notes:
1. The amplifier should be connected directly to a +9 V regulator; no dropping resistor is required.
2. If no DC signal is present at the input (pin 1), C1 can be removed. The gate (input pin) is internally grounded in the amplifier.
3. R1, C2, and L1 are used as placeholders for a different device on the same PCB layout. They are not needed for the AH101.
3. Component sizes are 0603 unless otherwise noted.
