RFS8 — 100 kHz to 8 GHz 8-Port RF Switch
The RFS8, a high-speed SP8T switch using SOI technology, supports RF switching up to 8 GHz with 100 ns rise/fall times, ideal for pseudo-doppler direction finding and multi-band sweeping. It operates from 100 kHz, making it perfect for automated testing, antenna polarization, satellite communications, WIFI, and cellular applications.
The RFS8 is an advanced single pole eight throw (SP8T) absorptive solid-state switch utilizing silicon-on-insulator (SOI) technology, designed for RF switching across eight ports up to 8 GHz. This versatile device supports switching from the LF band through to 8 GHz, making it ideal for pseudo-doppler direction finding applications. Its extremely fast switch speeds, with 100 ns rise/fall times and direct access from Spike, facilitate efficient multi-band sweeping and direction finding with the BB60D and SP145 spectrum analyzers.
Ideal for a variety of applications such as automated testing, multi-band sweeps, direction finding, antenna polarization, satellite communications, and industrial automation, the RFS8 is a reliable solution for high-speed RF switching. It features a broad frequency range starting at 100 kHz and offers 230 ns switch times, with frequency or interval switching supported by compatible hardware. This switch is also suitable for use in WIFI and cellular applications, providing dependable performance across diverse RF environments.
