Evaluation Board Details and Recommended Tuning Solutions— 2700-3600 MHz
Parts measured on evaluation board (8-mil thick
RO4003C). Electrical and thermal ground is
provided using copper-filled via hole array (not
pictured), and evaluation board is mounted to a
metal plate.
Matching is provided using lumped elements as
shown at left. Recommended tuning solutions for 3
frequency ranges are detailed in the parts list
below.
Bias Sequencing
Turning the device ON
1. Set V_G to the pinch-off (V_P), typically -5 V.
2. Turn on V_D to nominal voltage (50 V).
3. Increase V_GS until the I_DS current is reached.
4. Apply RF power to desired level.
Turning the device OFF
1. Turn the RF power off.
2. Decrease V_G down to V_P.
3. Decrease V_D down to 0 V.
4. Turn off V_G.
