RF Power Divider 500 MHz ~ 2 GHz Module (TTM Technologies 44000)

Part Overview

The TTM Technologies 44000 is an RF power divider module designed for operation across the 500 MHz to 2 GHz frequency range with a minimum isolation specification of 20 dB. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations. The module provides 1 dB insertion loss and is housed in a compact form factor measuring 4.000" L x 2.400" W x 0.370" H.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF power divider modules is determined by the following critical parameters:

• Frequency Range: Must cover or exceed 500 MHz ~ 2 GHz operation
• Insertion Loss: Must match or be lower than 1 dB
• Isolation Specification: Must meet or exceed 20 dB minimum isolation
• Package Type: Module configuration
• Moisture Sensitivity Level: Must be compatible with MSL 1 (Unlimited) handling

The identified substitute part meets the frequency range, insertion loss, and package requirements. However, the isolation specification differs from the original part, requiring engineering evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The Cinch Connectivity Solutions Midwest Microwave PWD-5520-08-SMA-79 provides functional equivalence in frequency range, insertion loss, and package configuration. The substitute part is currently in active production status, ensuring availability for procurement and support.

A key consideration is the isolation specification: the substitute part provides 15 dB minimum isolation compared to the original 20 dB specification. This 5 dB reduction in isolation performance must be evaluated against application requirements. The substitute part is RoHS non-compliant, whereas compliance status for the original part is not specified in the provided data.

Selection should be based on whether the 15 dB isolation specification meets the requirements of the target application and whether RoHS compliance is a system requirement.

Frequently Asked Questions (FAQ)

Q: Can the Cinch PWD-5520-08-SMA-79 be used as a direct replacement for the TTM Technologies 44000?

A: The Cinch part matches the frequency range, insertion loss, and package type. However, the isolation specification is 5 dB lower (15 dB vs. 20 dB). Direct substitution is possible only if the application can tolerate this reduction in isolation performance.

Q: What is the significance of the isolation specification difference?

A: Isolation determines the degree of signal separation between output ports. A lower isolation value means increased signal coupling between ports. Applications requiring high port-to-port rejection may not be suitable for the substitute part.

Q: Are there physical dimension differences between these modules?

A: Yes. The TTM Technologies 44000 measures 4.000" L x 2.400" W x 0.370" H, while the Cinch PWD-5520-08-SMA-79 measures 3.000" L x 4.000" W. Physical layout compatibility must be verified before substitution.

Q: Does RoHS compliance status affect substitution?

A: RoHS compliance is a regulatory and procurement consideration. The substitute part is RoHS non-compliant. If the application or end-use region requires RoHS compliance, this part may not be suitable regardless of electrical performance.

Q: What is the availability status of each part?

A: The TTM Technologies 44000 is obsolete with 894 units in stock. The Cinch PWD-5520-08-SMA-79 is active production with 829 units in stock, providing better long-term availability assurance.
