TS8242FK

RF Switches Overview

The TS8242FK is a single-pole four-throw (SP4T) reflective RF switch IC manufactured by TagoreTech. It operates within a frequency range of 1 MHz to 6 GHz and supports a maximum input power of 10 W. Key electrical specifications include an insertion loss of 0.5 dB, isolation of 20 dB, P1dB compression point of 45 dBm, and third-order intercept point (IIP3) of 74 dBm at a test frequency of 4 GHz. The device requires a supply voltage between 2.6 V and 5.25 V and functions in temperatures from -40°C to 85°C. It is housed in a 16-VFQFN package with dimensions of 3x3 mm.

RF Switches Procurement Notes

Verify the specific datasheet version provided by TagoreTech, as some distributor listings reference conflicting frequency ranges such as 30 MHz to 5 GHz versus the official 1 MHz to 6 GHz specification. Confirm that the 16-QFN(3x3) package matches the design-in requirements. Ensure compatibility with the 2.6V to 5.25V supply voltage range before finalizing procurement orders.

RF Switches Selection Notes

Select the TS8242FK when designing circuits requiring wideband switching up to 6 GHz with high power handling capabilities. The component is suitable for applications demanding low insertion loss and high isolation in compact form factors. Consider the reflective topology characteristics for impedance matching networks. Evaluate the thermal performance within the specified -40°C to 85°C operating range for environmental robustness.

RF Switches Part Context

The TS8242FK belongs to the Symmetric series of RF switches from TagoreTech. It is part of a portfolio including variants like the TS82420K, which shares similar power handling but may differ in frequency coverage or isolation metrics. The component serves as a core switching element in modern wireless communication hardware, supporting both legacy and next-generation cellular standards.

RF Switches Replacement Considerations

The TS82420K is a related variant within the same product family. While it shares the SP4T topology and similar power ratings, verify if its specific frequency range and isolation parameters meet the design requirements. No other direct cross-model substitutes are documented in the provided public data.
