SW-228-PIN

RF Switches Overview

The SW-228-PIN is a GaAs MMIC SPDT RF switch from MACOM Technology Solutions, designed for high-performance wireless applications. It operates within a frequency range of 0 Hz to 4 GHz and features a 50 Ohm impedance. The device provides a minimum isolation of 25 dB and a maximum insertion loss of 1.5 dB. Packaged in a lead-free, surface-mount CR-2 ceramic style package, it incorporates a PIN diode die fabricated with a low-loss, high-isolation switching process. This component offers low insertion loss characteristics suitable for cellular and GPS systems.

RF Switches Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as manufacturers may update revision levels or packaging configurations over time. Confirm that the received components match the active product status and technical specifications outlined in the official datasheet. Ensure compliance with RoHS directives and environmental standards required for your assembly process before final procurement approval.

RF Switches Selection Notes

Select the SW-228-PIN when low insertion loss is the primary requirement compared to other variants in the SW-226/227/228 series. Choose this part for applications requiring operation up to 4 GHz with standard 50 Ohm system impedance. Consider the CR-2 ceramic package for surface-mount assembly needs. Evaluate thermal management requirements based on the integrated bias network and power handling capabilities defined in the electrical specifications.

RF Switches Part Context

The SW-228-PIN belongs to a family of GaAs MMIC SPDT switches including the SW-226-PIN and SW-227-PIN. While the SW-226-PIN is a terminated switch and the SW-227-PIN focuses on high isolation, the SW-228-PIN is specifically engineered for low insertion loss. All three share the same CR-2 ceramic platform but offer distinct performance trade-offs tailored to different RF front-end architectures.

RF Switches Replacement Considerations

Direct substitutes within the same family include the SW-226-PIN and SW-227-PIN, though these offer different performance profiles such as termination or higher isolation rather than low loss. Verify pin compatibility and electrical parameter alignment before substitution. No alternative cross-brand replacements are confirmed in public documentation.
