RF Power Divider 2 GHz–4 GHz Module (TTM Technologies 40266)

Part Overview

The TTM Technologies 40266 is an RF power divider module designed for operation in the 2 GHz to 4 GHz frequency band with a minimum isolation specification of 20 dB. This component is classified as obsolete, making identification of suitable substitute parts necessary for ongoing system support and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TTM Technologies 40266 is based on the following critical electrical and mechanical parameters:

• Frequency Range: Substitute parts must operate across the full 2 GHz to 4 GHz band
• Isolation Specification: Minimum 20 dB isolation is required for functional equivalence
• Package Type: Module-level packaging maintains mechanical and thermal compatibility
• Moisture Sensitivity: MSL 1 rating ensures handling and storage compatibility

The Cinch Connectivity Solutions Midwest Microwave PWD-5512-T2-NNN-79 meets these substitution criteria. While insertion loss is specified at 0.4 dB (compared to 0.3 dB for the original part), this represents a 0.1 dB increase within acceptable system design margins for most RF applications in this frequency band.

Parameter Comparison

Engineering Selection Recommendations

The Cinch Connectivity Solutions Midwest Microwave PWD-5512-T2-NNN-79 is the qualified substitute for the obsolete TTM Technologies 40266. The substitute part maintains electrical equivalence across all critical parameters: frequency range, isolation specification, and moisture sensitivity classification.

The primary difference is insertion loss (0.4 dB versus 0.3 dB). This 0.1 dB increase must be evaluated within the context of system link budgets and overall RF chain performance requirements. For applications where insertion loss is a critical constraint, system-level analysis is necessary to confirm acceptable performance.

The substitute part carries active product status, ensuring ongoing availability and manufacturer support. RoHS non-compliance of the substitute should be evaluated against application requirements and regulatory obligations.

Frequently Asked Questions (FAQ)

Q: Can the Cinch PWD-5512-T2-NNN-79 be used as a direct replacement for the TTM 40266?

A: Yes, provided that the 0.1 dB increase in insertion loss is acceptable for your system design. Both parts meet the frequency range and isolation specifications required for functional equivalence.

Q: What is the significance of the insertion loss difference?

A: The TTM 40266 specifies 0.3 dB insertion loss while the Cinch substitute specifies 0.4 dB. This 0.1 dB difference represents approximately 2.3% additional signal attenuation. System link budget analysis determines whether this is acceptable for your application.

Q: Are there mechanical compatibility concerns between these parts?

A: The TTM 40266 measures 2.100" L × 1.250" W × 0.370" H. The Cinch substitute measures 2.350" L × 1.070" W. Physical dimensions differ; mechanical fit and mounting compatibility must be verified for your specific application.

Q: What does MSL 1 (Unlimited) mean for handling?

A: MSL 1 classification indicates the component is not moisture-sensitive and requires no special storage or handling precautions. Both the original and substitute parts carry this classification.

Q: Why is the TTM 40266 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Cinch substitute maintains active product status, ensuring continued availability for new designs and system support.
