Alternatively, the jumper JP1 can be removed to supply

an external gate voltage on the J1 connector

HOW TO GET STARTED

If the fixture is a new build:

1. Set gate bias to minimum by turning pot fully clockwise (12 turns).

2. Remove JP1 and check drain DC power terminal using an ohmmeter: DC power

terminal should read a high impedance.

3. Replace JP1.

Initial power on:

1. Mount baseplate onto a heatsink capable of dissipating more than 100 W.

2. Terminate RF output with a 50 ohm load capable of dissipating more than 330 W.

3. Connect RF input to a 50 ohm source with RF off.

4. Ensure the drain DC is set to 0 V.

5. Connect ground, drain DC.

6. Raise drain DC slowly to 50 Vdc. Current should be 0 A.

7. Adjust gate bias to desired target current, typically 50-500 mA.

8. Slowly increment RF input power source not exceeding 1 W. Monitor drain DC

current and RF output power (typically less than 10 A max at 300 W).

9. Check drain DC current, RF output power and temperature.

Shutdown:

1. Shut off RF input power.

2. Remove drain DC voltage.

Assembly notes:

• Mount all SMT devices on PCB (device values are dependent on frequency

of operation).

• Make sure no solder blobs are on non-component side of board.

• Trim leads of MRF300AN to shoulder.

• Mount board onto baseplate.

• Mount device using thermal grease, solder only after tightening device

mounting screw.

• Mount connectors and solder center pins.

• Connect power wires
