BMLPV1700 RF Antenna Equivalent & Substitute Parts

Part Overview

The BMLPV1700 is a 2.1GHz general purpose dome RF antenna manufactured by PCTEL, Inc., designed for wide-band applications across the 1.7GHz to 2.5GHz frequency range. This antenna operates at 4dBi gain with a VSWR of 1.5 and is rated for 100W maximum power with IP67 ingress protection. The product is currently listed as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The BMLPVDB800/1900S is identified as the manufacturer-recommended substitute for the BMLPV1700. Substitution eligibility is determined by the following critical parameters:

Substitution Criteria:

• Antenna type classification (Dome)
• Frequency band overlap within the original operating range
• Gain compatibility (4dBi available in substitute)
• Power rating (100W maintained)
• Ingress protection rating (IP67 maintained)
• Manufacturer series continuity (MLPV series)

The BMLPVDB800/1900S operates across two frequency bands: 806MHz ~ 960MHz and 1.71GHz ~ 1.99GHz. The upper frequency band (1.71GHz ~ 1.99GHz) overlaps with the lower portion of the BMLPV1700 operating range, providing functional coverage for applications requiring operation in the 1.7GHz to 1.99GHz window. The substitute maintains dome antenna architecture, identical power rating, and equivalent ingress protection.

Parameter Comparison

Engineering Selection Recommendations

The BMLPVDB800/1900S is the manufacturer-designated substitute for the obsolete BMLPV1700. Selection of this substitute is appropriate for applications operating within the 1.71GHz to 1.99GHz frequency band, where the substitute provides active product status and continued manufacturer support. The substitute maintains critical electrical parameters including 100W power rating and IP67 environmental protection.

Applications requiring operation above 1.99GHz up to the original 2.5GHz specification cannot be fully supported by the BMLPVDB800/1900S, as the substitute's upper frequency limit is 1.99GHz. In such cases, alternative components outside the provided substitute list must be evaluated.

The VSWR specification differs between the two antennas (1.5 versus 2), representing a measurable change in impedance matching characteristics. System designs sensitive to return loss performance should account for this parameter variance.

Frequently Asked Questions (FAQ)

Q: Can the BMLPVDB800/1900S replace the BMLPV1700 in all applications?

A: The BMLPVDB800/1900S is suitable for applications operating within the 1.71GHz to 1.99GHz frequency range. Applications requiring operation above 1.99GHz are not fully supported by this substitute.

Q: What is the primary difference in VSWR between these antennas?

A: The BMLPV1700 specifies VSWR of 1.5, while the BMLPVDB800/1900S specifies VSWR of 2. This represents a difference in impedance matching performance. Systems with strict return loss requirements should evaluate this parameter.

Q: Does the BMLPVDB800/1900S maintain the same mounting interface?

A: The BMLPV1700 uses threaded mounting, while the BMLPVDB800/1900S offers multiple mounting options: connector mount, NMO, stud, and through hole. Mechanical integration requires verification of the specific mounting configuration needed for your application.

Q: What is the product status difference between these parts?

A: The BMLPV1700 is obsolete with no ongoing manufacturer support. The BMLPVDB800/1900S is active, ensuring continued availability and manufacturer technical support.

Q: Are the gain specifications compatible?

A: The BMLPV1700 provides 4dBi gain. The BMLPVDB800/1900S provides both 3dBi and 4dBi gain options, with 4dBi available for direct gain matching.
