The amplifier should be connected directly to a +11 V regulator; no dropping resistor is required.

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.

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-180X_B) is recommended.

C7 is located between silk screen markers “ 5” and “ 6” on the WJ evaluation board.
