R573813640 RF Switch IC SP6T 40GHz Equivalent & Substitute Parts

Part Overview

The R573813640 is an RF Switch IC featuring a single-pole six-throw (SP6T) topology designed for general-purpose RF applications operating across the 0Hz to 40GHz frequency range. This active product from Radiall USA, Inc. provides 50Ohm impedance matching with 50dB minimum isolation and 1.1dB maximum insertion loss at the 40GHz test frequency. The component operates from a 24V to 30V supply and functions across the -40°C to 85°C temperature range in a module package format. Substitute parts are identified to address inventory availability, specific circuit topology requirements, or alternative sourcing needs while maintaining critical RF performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R573813640 are identified based on strict alignment with the following critical parameters: frequency range capability (0Hz ~ 40GHz), impedance matching (50Ohm), isolation performance (50dB minimum), insertion loss specification (1.1dB maximum), supply voltage range (24V ~ 30V), operating temperature range (-40°C ~ 85°C), package format (Module), and active product status with ROHS3 compliance.

The substitute parts differ in circuit topology (SP3T, SP4T, or SP6T configurations), which determines the number of throw positions available. The R573803320 provides SP3T functionality, the R573883400 provides SP4T functionality, and the R573883600 provides SP6T functionality identical to the main part. All substitutes maintain identical RF performance characteristics, electrical specifications, and environmental operating conditions. Selection among substitutes depends on the specific number of switch positions required by the application circuit design.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain identical RF performance specifications across the 0Hz to 40GHz frequency range with matching 50Ohm impedance, 50dB isolation, and 1.1dB insertion loss characteristics. The primary differentiation factor is circuit topology: the R573813640 and R573883600 both provide SP6T (six-throw) configurations, while the R573803320 provides SP3T (three-throw) and the R573883400 provides SP4T (four-throw) configurations.

For direct functional replacement requiring six switch positions, the R573883600 serves as the equivalent substitute, offering identical SP6T topology with ROHS3 compliance and active product status. The R573883600 maintains all electrical and environmental specifications of the main part.

For applications requiring fewer switch positions, the R573803320 (SP3T) and R573883400 (SP4T) are suitable alternatives provided the circuit design accommodates the reduced number of throw positions. Both alternatives maintain full RF performance parity and environmental operating specifications.

All parts are manufactured by Radiall USA, Inc., operate from identical 24V to 30V supply voltages, function across the -40°C to 85°C temperature range, and are packaged in module format. Selection should be based on the specific number of switch positions required by the application circuit topology.

Frequently Asked Questions (FAQ)

Q: Can the R573883600 directly replace the R573813640?

A: Yes. Both parts feature identical SP6T topology, frequency range (0Hz ~ 40GHz), impedance (50Ohm), isolation (50dB minimum), insertion loss (1.1dB maximum), supply voltage range (24V ~ 30V), operating temperature range (-40°C ~ 85°C), and module package format. Both are ROHS3 compliant and active products from Radiall USA, Inc.

Q: What is the difference between the SP3T, SP4T, and SP6T configurations?

A: The designations indicate the number of throw positions available in the switch. SP3T provides three throw positions, SP4T provides four throw positions, and SP6T provides six throw positions. The selection depends on the number of signal paths required by the application circuit.

Q: Are all substitute parts rated for the same frequency range?

A: Yes. All substitute parts (R573803320, R573883400, and R573883600) operate across the identical 0Hz to 40GHz frequency range with matching 50Ohm impedance and 50dB minimum isolation specifications.

Q: Do all substitute parts operate from the same supply voltage?

A: Yes. All substitute parts require a 24V to 30V supply voltage range, identical to the R573813640 main part.

Q: What is the operating temperature range for all parts?

A: All parts operate across the -40°C to 85°C temperature range.

Q: Are all substitute parts ROHS3 compliant?

A: The R573813640, R573883400, and R573883600 are specified as ROHS3 compliant. The R573803320 RoHS status is not specified in the provided data.

Q: What package format do all these parts use?

A: All parts are supplied in module package format.

Q: If my application requires only three switch positions, can I use the R573803320?

A: Yes, provided your circuit design accommodates the SP3T topology. The R573803320 maintains all RF performance specifications, supply voltage requirements, operating temperature range, and impedance matching of the main part.
