RF Power Divider 42020 Equivalent & Substitute Parts

Part Overview

The TTM Technologies 42020 is an RF power divider module designed for operation across the 2 GHz to 8 GHz frequency range with a minimum isolation specification of 18dB. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations. The module provides 0.7dB insertion loss and is housed in a compact form factor measuring 1.500" L x 1.000" 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: The substitute must cover the full 2 GHz to 8 GHz operating band
• Isolation Performance: The substitute must meet or exceed the 18dB minimum isolation requirement
• Package Type: Module-based construction to maintain form factor compatibility
• Insertion Loss: Lower insertion loss values indicate improved performance
• Moisture Sensitivity Level: MSL rating of 1 ensures handling compatibility

The PWD-5522-02-SMA-79 meets all substitution criteria, offering improved electrical performance with 20dB isolation and 0.5dB insertion loss while maintaining the same frequency coverage and module packaging.

Parameter Comparison

Engineering Selection Recommendations

The PWD-5522-02-SMA-79 is the qualified substitute for the obsolete 42020. This part is currently in active production status, ensuring long-term availability and supply chain continuity. Both components share identical ECCN classification (EAR99), maintaining regulatory compliance for export and distribution.

The PWD-5522-02-SMA-79 demonstrates superior electrical performance with 2dB additional isolation margin and 0.2dB lower insertion loss compared to the original 42020. These improvements provide enhanced signal separation and reduced signal degradation across the 2 GHz to 8 GHz operating band.

Frequently Asked Questions (FAQ)

Q: Can the PWD-5522-02-SMA-79 directly replace the 42020 in existing designs?

A: Yes. Both components operate across the identical 2 GHz to 8 GHz frequency range, maintain the same module packaging, and share MSL 1 moisture sensitivity classification. The substitute meets or exceeds all electrical specifications of the original part.

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

A: The PWD-5522-02-SMA-79 offers improved isolation performance (20dB versus 18dB) and lower insertion loss (0.5dB versus 0.7dB). The substitute is currently in active production, whereas the 42020 is obsolete. Physical dimensions differ slightly, with the substitute measuring 2.000" L x 1.000" W.

Q: Are there compliance or regulatory differences?

A: Both components share the same ECCN classification (EAR99) and MSL rating (1). The PWD-5522-02-SMA-79 is RoHS non-compliant, which should be verified against your system requirements.

Q: What is the significance of the isolation specification in this substitution?

A: Isolation determines the degree of signal separation between output ports. The PWD-5522-02-SMA-79 provides 20dB isolation compared to the 42020's 18dB minimum, indicating superior port-to-port signal rejection and reduced crosstalk.

Q: Does insertion loss affect system performance?

A: Insertion loss represents signal attenuation through the divider. The PWD-5522-02-SMA-79's 0.5dB loss versus the 42020's 0.7dB results in less signal degradation, improving overall system efficiency and signal integrity across the operating frequency range.
