BSW7221

RF Switches Overview

The BSW7221 is a single-pole double-throw (SPDT) RF switch IC manufactured by BeRex Corp, designed for high-linearity applications in wireless communication systems. It operates within a frequency range of 5MHz to 8GHz and supports multiple standards including 5G NR, Cellular, LTE, PCS, WCDMA, and WiMAX. The device features a 50-ohm impedance and utilizes a compact 6-UDFN (1.5x1.5mm) surface-mount package with an exposed pad. Key electrical specifications include a maximum insertion loss of 0.64dB, isolation of 29dB, P1dB compression point of 35dBm, and third-order input intercept point (IIP3) of 64dBm. It functions on a supply voltage of 2.7V to 3.6V and maintains operation across a temperature range of -40°C to 105°C.

RF Switches Procurement Notes

Verify component authenticity through authorized BeRex Corp distributors or certified suppliers. Confirm that the received parts match the specific 6-UDFN package dimensions and pinout configuration. Ensure storage conditions comply with moisture sensitivity level 1 requirements to prevent package damage prior to reflow soldering. Cross-reference ordering information with official manufacturer documentation to avoid counterfeit components.

RF Switches Selection Notes

Select this component when designing RF front-ends requiring high linearity and low loss within the 5MHz to 8GHz spectrum. The SPDT topology is suitable for antenna switching or signal routing in multi-standard transceivers. Consider the 6-UDFN footprint for PCB layout constraints and verify thermal dissipation capabilities given the exposed pad requirement. Ensure supply voltage compatibility with the 2.7V to 3.6V operating range.
