D4 – SP4T Octave and Broadband

MCLI offers fast switching solutions through its pin diode switch product line. A diverse range of multiport models are currently accessible in the market, extending up to SP8T (Single Pole 8 Throw), that offer distinguished characteristics such as high isolation, low insertion loss, and rapid switching times of up to 100 nanoseconds. The absorptive models are equipped with 50-ohm terminations at each of their output ports to ensure a low voltage standing wave ratio (VSWR) in both the on and off states. Reflective models perform the function of conducting RF power in a reverse-biased diode configuration and reflecting RF power in a forward-biased switch configuration.
