Integration and Bias Notes
The published RF performance is specified for pulsed operation with a 50µs pulse width and 5% duty cycle.
Do not interpret the 57dBm rating as a verified CW output-power rating.
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.
Maintain a minimum 0.1mm lead-to-PCB height and keep the package temperature at or below +75°C.
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 frequency range does the IMPA009012P57 cover?
The specified operating range is 0.96GHz to 1.22GHz.
What is the minimum saturated output power?
The specified minimum saturated output power is 57dBm under the stated +50V pulsed test conditions.
What pulse conditions apply to the published performance?
The published values use a 50µs pulse width and a 5% duty cycle at an ambient temperature of +25°C.
Can the 57dBm rating be treated as a CW rating?
No. The supplied datasheet validates the principal RF performance under pulsed conditions and does not provide a verified 57dBm CW rating.
What gain and efficiency are specified?
The device provides at least 13.5dB power gain and at least 57% power-added efficiency under the specified pulse conditions.
B2B Procurement FAQ
What application information should be supplied with an RFQ?
Please provide the operating frequency, pulse width, duty cycle, required output power, quantity, destination country and any documentation requirements.
Can samples be ordered for pulsed RF evaluation?
Sample availability and lead time should be confirmed during quotation. The evaluation setup should reproduce the specified bias and pulse conditions.
Is a recommended application circuit included?
Yes. The supplied documentation includes a recommended circuit using RO4350B RF laminate.
Can CW performance be requested?
A separate technical confirmation would be required because the supplied datasheet does not specify the headline output-power rating for CW operation.
Are minimum order quantity and delivery time specified?
No fixed minimum order quantity or delivery commitment appears in the supplied material. These terms should be confirmed for each quotation.
