Integration and Bias Notes
Apply the negative gate bias before applying the positive drain voltage.
During power-down, remove the drain voltage before removing the gate bias.
Use M2.0 mounting screws with a recommended tightening torque of 0.6N·m.
Provide a mounting slot width of at least 17.65mm and maintain a minimum 0.1mm lead-to-PCB height.
Keep the package temperature at or below +85°C during operation.
The reference circuit uses RO4350B material with 0.762mm thickness and a dielectric constant of 3.48.
The device is electrostatic-discharge sensitive; use grounded handling and assembly equipment.
FAQ
What is the specified frequency range of the IMPA008020P40?
The specified operating range is 0.8GHz to 2.0GHz. The supplied characterization table also contains measurements from 0.5GHz to 0.7GHz, but those points are outside the stated operating band.
