RF Power Divider 6 GHz–18 GHz Module 43040

Part Overview

The TTM Technologies, Inc. model 43040 is an RF power divider module designed for operation across the 6 GHz to 18 GHz frequency band. This component provides signal distribution with minimum isolation of 17 dB and 14 dB return loss characteristics. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TTM Technologies 43040 is determined by alignment across the following critical parameters:

• Frequency Coverage: The substitute must operate across the full 6 GHz to 18 GHz band
• Isolation Performance: Minimum isolation specification must meet or exceed 17 dB
• Insertion Loss: Performance at or below 0.7 dB is required for signal integrity
• Package Configuration: Module-level packaging with compatible physical form factor
• Moisture Sensitivity: MSL rating of 1 or equivalent

The Cinch Connectivity Solutions Midwest Microwave PWD-5526-02-SMA-79 satisfies these substitution criteria across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The Cinch PWD-5526-02-SMA-79 is the designated substitute for the obsolete TTM 43040. Selection is based on the following factors:

• Product Status: The TTM 43040 is obsolete; the Cinch part maintains active production status, ensuring long-term availability and supply chain continuity
• Performance Alignment: The Cinch substitute meets all specified electrical parameters, with improved insertion loss (0.5 dB versus 0.7 dB) and enhanced isolation (18 dB versus 17 dB minimum)
• Regulatory Compliance: Both components share identical REACH and ECCN classifications, maintaining compliance posture across export and environmental regulations
• Packaging and Handling: Moisture sensitivity levels are equivalent, requiring no changes to storage or handling procedures

Frequently Asked Questions (FAQ)

Q: Can the Cinch PWD-5526-02-SMA-79 be used as a direct replacement for the TTM 43040?

A: Yes. The Cinch part meets all critical electrical specifications across the 6 GHz to 18 GHz frequency band, with equivalent or superior performance in insertion loss and isolation characteristics.

Q: What are the key differences between these two modules?

A: The primary differences are product status (TTM is obsolete; Cinch is active), insertion loss (0.5 dB versus 0.7 dB), and isolation performance (18 dB versus 17 dB minimum). Physical dimensions differ slightly, with the Cinch part measuring 1.000" × 1.000" versus the TTM part at 1.510" × 1.000".

Q: Are there any compliance or regulatory concerns with substitution?

A: No. Both components share identical REACH and ECCN classifications (EAR99), and both maintain MSL 1 moisture sensitivity ratings, requiring no changes to procurement, handling, or export procedures.

Q: Does the smaller physical footprint of the Cinch part affect compatibility?

A: Physical dimensions must be verified against your specific mechanical integration requirements. The Cinch PWD-5526-02-SMA-79 is smaller in length and width, which may require mechanical redesign depending on mounting constraints.

Q: What is the availability status of each part?

A: The TTM 43040 is obsolete with 929 units in current inventory. The Cinch PWD-5526-02-SMA-79 is active production with 1,072 units in inventory, providing superior long-term supply assurance.
