VAUNIX LSW-802P4T SP4T RF Switch – available from bq-microwave
With the VAUNIX LSW-802P4T, bq-microwave expands its Lab Brick portfolio with a high-performance absorptive SP4T RF switch. This solid-state switch covers the full 100 to 8000 MHz range and delivers phase-matched, repeatable switching for demanding test and measurement tasks.
What sets the LSW-802 series apart
The LSW-802P4T is a 50-Ω single-pole four-throw switch in an absorptive design: inactive outputs are internally terminated in 50 Ω, which minimizes reflections and stabilizes behavior in complex measurement chains. The four outputs are phase-matched, so path changes occur without uncontrolled phase jumps. Switching takes just 50 ns.
