Notes:

The amplifier should be connected directly to a +11 V regulator; no dropping resistor is required.
Component sizes are 0603 unless otherwise noted. RF choke L1 should be wirewound ceramic type to insure sufficient current carrying
capacity. Coilcraft’s 1008 CS series (part # 1008CS-220X_B) is recommended.
C7 is located between silk screen markers “6” and “7” on the WJ evaluation board.
