TS8423K SPDT RF Switch IC – 1MHz–7.2GHz 20W 16-QFN

TS8423K RF Switch IC – Symmetric Reflective SPDT, 1MHz–7.2GHz, 20W Peak Power, 16-QFN 3×3

The TS8423K is a symmetric reflective Single Pole Dual Throw (SPDT) RF switch designed for broadband, high peak-power switching applications. Its operating range covers 1 MHz to 7.2 GHz, with guaranteed broadband performance from 30 MHz to 5.0 GHz — making it a workhorse switch for any RF signal path that requires low insertion loss, high isolation and high linearity within a compact package. The 16-QFN 3 × 3 mm footprint and 50 Ω system impedance drop it directly into standard RF layouts without matching networks.

Stocking part for RF integrators building or repairing 5G, cellular, tactical-radio and datalink hardware — new and original devices, tray-quantity supply available for production runs and bench spare stock.

Typical Use Cases

• Cellular front-end switching — antenna / band switching in cellular transceivers.
• Datalink RF paths — TX/RX switching in wireless data infrastructure.
• Tactical radio — high peak-power SPDT switching in software-defined radios and combat-radio modules.
• 5G small cells & test equipment — antenna switching, receiver protection, calibration paths.
• RF bench stock — general-purpose broadband SPDT for lab and repair.

Broadband Performance & 20 W Peak Handling

What sets the TS8423K apart in this class of switch is the combination of broadband coverage from 30 MHz through 5.0 GHz (with usable performance extending 1 MHz to 7.2 GHz) and 20 W peak power handling. Symmetric reflective SPDT topology keeps insertion loss low in both paths and isolation high between the two throws, which is what allows a designer to use a single part across cellular, datalink and tactical-radio applications instead of stocking separate switches for each band or power class.

TS8423K Specifications

FAQ — TS8423K RF Switch

Q: Full operating vs guaranteed broadband range?
A: The TS8423K operates from 1 MHz to 7.2 GHz, with the manufacturer's guaranteed broadband performance envelope specified from 30 MHz to 5.0 GHz. Outside the guaranteed range, verify insertion loss and isolation against your specific application requirements on the datasheet.

Q: Substitute parts?
A: Other symmetric reflective SPDT switches with matching 50 Ω / broadband / peak-power specification in a comparable QFN footprint. Match insertion loss, isolation, and peak-power handling to the TS8423K before designing in.
