MA4SW210B-1

RF Switches Overview

The MA4SW210B-1 is a broadband SPDT RF switch IC from MACOM Technology Solutions, operating within a frequency range of 2 GHz to 18 GHz. Utilizing the Heterolithic Microwave Integrated Circuit (HMIC) process with integrated silicon PIN diodes, this component features an integrated bias network for simplified circuit design. It provides typical off-isolation of 40 dB and insertion loss of 1.2 dB at 18 GHz. The device supports a wide operating temperature range from -65°C to +125°C and is supplied in a bare die package configuration.

RF Switches Feature Summary

• Integrates silicon PIN diodes with a dedicated bias network using HMIC technology
• Provides single-pole double-throw (SPDT) switching topology for signal routing
• Operates as a series-shunt broadband switch without requiring external bias components

RF Switches Applications

• Broadband RF signal routing in communication systems
• Antenna switching networks for multi-band transceivers
• Test and measurement equipment requiring high-isolation switching

RF Switches Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm the exact electrical characteristics and pinout configuration. Ensure that the procurement channel supplies genuine MACOM Technology Solutions products with appropriate traceability. Confirm that the receiving facility has the necessary capabilities for handling bare die components, including proper mounting and wire bonding procedures compatible with the specified package type.

RF Switches Selection Notes

Select this component when a compact SPDT solution with integrated biasing is required for frequencies up to 18 GHz. The integrated bias network reduces external component count compared to discrete PIN diode implementations. Consider the bare die format for applications where board space is limited and custom packaging or direct mounting is feasible. Evaluate thermal management requirements given the extended operating temperature range and power dissipation characteristics inherent to the silicon PIN diode structure.

RF Switches Part Context

This part belongs to the MA4SW series of broadband switches manufactured by MACOM Technology Solutions. The series includes variants such as the MA4SW110 (SPST), MA4SW310 (SP3T), and MA4SW410 (SP4T). These devices share common underlying HMIC technology but differ in port configuration and specific performance metrics. The B-1 suffix typically denotes a specific revision or configuration within the SPDT category, distinguishing it from earlier generations like the standard MA4SW210.

RF Switches Replacement Considerations

The MA4SW210 is a related SPDT variant within the same product family. Verify compatibility regarding frequency range, isolation levels, and bias requirements before substitution. Other series members include the MA4SW110, MA4SW310, and MA4SW410.
