Biasing Notes
1. Dual bias is required
2. 0.1µF bypass capacitors are needed on PC board as close as possible to pins
1, 5, 6 and 10.
3. Positive (+) bias can be applied either at pin 1 or pin 6.
4. Negative (-) bias can be applied either at pin 5 or pin 6.
5. No DC block is required at RF IN/OUT.
6. Negative (-) bias must be applied before applying positive (+) bias.
Mounting Recommendations
1. Leads should be as short as possible.
2. Solder all leads on PC board. Solder area should be as small as possible.
Grounds should be provided for pins 2, 4, 7, and 9 on PC boards.
3. Flange should be screwed down on adequate heat sink. Do not over torque
screws in order to avoid breaks in ceramic and die (tightening torque: 6lbf-in).
4. Grounding shims should be placed between the flange and heat sink to ensure
optimal ground contact. Aluminum or Copper foil can be used.
5. 50Ω RF IN/OUT interface are required for optimal electrical performance.
6. Due to the high gain of this device it is highly recommended to maintain the
reverse isolation (S12) above 50 dB.
