ADT1.5-17+ datasheet by Mini-Circuits

ADT1.5-17+ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Mini-Circuits recommends a 50-ohm microstrip line with a 0.5mm to 1.5mm wide trace and a 0.5mm to 1.5mm gap between the trace and the ground plane. A 4-layer PCB with a solid ground plane is also recommended.
• How do I ensure proper thermal management for the device?
  The device has a thermal pad on the bottom that should be connected to a solid ground plane or a thermal via to dissipate heat. A thermal interface material (TIM) can also be used to improve heat transfer.
• What is the maximum operating temperature range for the device?
  The device is rated for operation from -40°C to +85°C, but it's recommended to derate the power handling by 1 dB for every 10°C above 70°C to ensure reliability.
• Can I use the ADT1.5-17+ in a push-pull configuration?
  Yes, the device can be used in a push-pull configuration, but it's essential to ensure that the two devices are properly matched and biased to avoid uneven current sharing and potential oscillations.
• What is the recommended biasing scheme for the device?
  Mini-Circuits recommends a voltage-controlled current source biasing scheme, with a voltage regulator and a current sense resistor to set the desired bias current.
