Technical Specifications

Key specifications of the IAX Series include:

Impedance: 50Ω Nominal

VSWR (Voltage Standing Wave Ratio): Maximum of 1.3:1 up to 18 GHz.

DC Attenuation Stability: 0.001dB per dB per degree Celsius.

Operating Temperature: Ranges from -55°C to 150°C.

Attenuation Details

Accuracy (DC): Ranges from +/- 0.2dB to +/- 0.5dB depending on the attenuation value.
Increment Accuracy (dB): Maintains tolerances defined within 0.2dB for precision.

Product Design and Construction

The IAX Series utilizes a thick film on 96% Alumina substrate, ensuring durable and reliable performance. They can be attached using soldering, epoxy, or wire-bond, accommodating various assembly requirements.

Ordering and Compliance

Customers can specify their needs using a defined ordering instruction format which includes the prefix for attenuators, value in dB, termination metallization, power, case size, and termination style. The termination options include Au, PtAg, and PtAg with various solder types. It is important to note that ground pads must be shorted during assembly to ensure proper functionality. The products produced by International Manufacturing Services, Inc. are compliant with RoHS standards, as indicated by specific symbols in the documentation.
