ASWD-S2-0003-T

RF Switches Overview

The ASWD-S2-0003-T is an SPDT RF switch IC from Abracon, utilizing GaAs technology. It operates within a frequency range of 0.1 to 2.7 GHz (up to 3 GHz per some sources). Key electrical parameters include typical insertion loss of 0.35 dB at 0.1–1 GHz and 1.6 dB at higher frequencies within the band. Isolation is typically 30 dB. The device supports a maximum control voltage of 3.6 V and functions between -40°C and +85°C. It is housed in a compact SOT-363 (SC70-6) package measuring 2.0mm x 1.2mm.

RF Switches Procurement Notes

Verify the specific datasheet revision for the ASWD-S2-0003-T to confirm exact insertion loss values at target frequencies, as specifications vary slightly between 0.1-2.7 GHz and extended 0.1-3.0 GHz ranges. Ensure thermal management aligns with the -40°C to +85°C operating limit. Confirm package footprint compatibility with the SC70-6/SOT-363 land pattern before finalizing procurement.

RF Switches Selection Notes

Select this component when a low-profile SPDT switch is required for sub-3 GHz applications. The GaAs technology offers high linearity and low noise compared to silicon alternatives. Consider the 3.6V control voltage requirement for logic interface compatibility. The SOT-363 package is suitable for space-constrained mobile and IoT designs requiring integrated ESD protection.

RF Switches Part Context

This part belongs to Abracon's ASWD-S2 series of wideband high-linearity RF switches. The series includes variants like ASWD-S2-0009-Q-T which extends frequency coverage up to 8.5 GHz. The ASWD-S2-0003-T specifically targets lower frequency bands, offering a balance of performance and size for cellular and wireless connectivity modules.

RF Switches Replacement Considerations

Publicly confirmed direct substitutes are not explicitly listed in the provided source material. Designers should evaluate other GaAs SPDT switches in the SOT-363 package with similar 0.1-3 GHz bandwidth and 30 dB isolation specs if replacement is necessary.
