Signal Hound, renowned for its accessible, versatile, and precise test equipment, recently unveiled the latest addition to its growing product range – the RFS44. 

This high-performance, ultra-swift antenna switch is now in stock and ready for immediate order. The RFS44 is a single pole four throw (SP4T) absorptive solid-state switch. Leveraging silicon-on-insulator (SOI) technology, it facilitates RF switching across four ports at frequencies of up to 44 GHz.

“The RFS44 allows engineers to switch from LF all the way through the Ka band and utilise this versatile tool in pseudo-doppler direction finding applications,” said Justin Crooks, Senior Engineer, Signal Hound. “With ultra-fast switch speed, 3 ns rise/fall times, and direct access from our proprietary Spike software, the RFS44 enables multi-band sweeping and direction finding to the SP145 as well as the SM200 and SM435 product lines.”

The RFS44 4-Port Antenna Switch operates at a frequency range of 100 kHz to 44 GHz, is direct logic control enabled, boasts a 20 ns switch time, and allows for frequency or interval switching with supported hardware. With a standard operating temperature range of -40°F to 185°F (-40°C to +85°C), the RFS44 weighs only 8.9 oz. (0.25 kg) and measures only 4.09” x 4.17” x 1.32” (104mm x 106mm x 34mm).
