Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GD35-25P-NF is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Frequency range: 3.4GHz ~ 3.6GHz (center 3.5GHz)
• Antenna type: Parabolic Grid
• Gain: 25dBi
• VSWR: 1.5
• Power rating: 100 W maximum
• Mounting type: Bracket Mount
• Cable length: 762mm
• Height: 36.000" (914.40mm)
• Base product number: GD35

Allowed Variation:

• Termination type: N Type connector gender (Female or Male) may differ based on system interface requirements

The GD35-25P-NM qualifies as a direct substitute with the single exception of termination connector gender, changing from N Type Female to N Type Male. All other electrical and mechanical parameters remain identical.

Engineering Selection Recommendations

GD35-25P-NM Selection Criteria:

The GD35-25P-NM is the active equivalent substitute for the obsolete GD35-25P-NF. Selection of this substitute is appropriate when:

1. System Interface Compatibility: The receiving equipment or transmission line interface requires N Type Male connector termination rather than N Type Female. Connector gender must be verified against the mating interface before deployment.

2. Compliance and Certification: Both parts maintain identical RoHS compliance status and regulatory certifications (ECCN: 5A991G; HTSUS: 8529.10.9100), ensuring equivalent regulatory standing for procurement and deployment.

3. Supply Chain Continuity: The GD35-25P-NM maintains active product status with 1130 units in stock, compared to the obsolete GD35-25P-NF with limited remaining inventory of 806 units. For new system designs and long-term field support, the GD35-25P-NM provides assured supply availability.

4. Electrical and Mechanical Equivalence: All RF performance parameters, mechanical dimensions, power handling, and mounting specifications are identical between the two models, ensuring drop-in compatibility at the antenna level when connector gender is accommodated.

Frequently Asked Questions (FAQ)

Q: Can the GD35-25P-NM directly replace the GD35-25P-NF without any modifications?

A: Direct replacement depends on connector interface compatibility. The GD35-25P-NM features N Type Male termination while the GD35-25P-NF features N Type Female termination. If the system interface requires N Type Female, an adapter or cable modification is necessary. If the system interface requires N Type Male, direct installation is possible without modification.

Q: Are the RF performance characteristics identical between GD35-25P-NF and GD35-25P-NM?

A: Yes. Both antennas operate at 3.5GHz center frequency with 3.4GHz to 3.6GHz bandwidth, deliver 25dBi gain, maintain 1.5 VSWR, and handle 100W maximum power. Frequency response, radiation pattern, and impedance matching are equivalent.

Q: Why is the GD35-25P-NF classified as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The GD35-25P-NM remains in active production, providing continued support for 3.5GHz WiMax™ parabolic grid antenna applications.

Q: What is the significance of the cable length specification (762mm)?

A: The 762mm cable assembly is integral to the antenna package and is identical on both the GD35-25P-NF and GD35-25P-NM. This cable length is a fixed component and cannot be altered without affecting the product specification.

Q: Are there any differences in mechanical mounting between these two models?

A: No. Both models feature identical bracket mount configuration, 36-inch (914.40mm) maximum height, and mounting interface specifications.

Q: What connector adapter options exist if system interface gender does not match?

A: Connector gender mismatch requires either an N Type Male-to-Female adapter or replacement of the antenna cable assembly with a compatible termination. Adapter specifications must be verified for impedance matching and power rating compatibility with the 100W maximum power specification.
