Pasternack RF switches are passive microwave devices that route a high frequency RF signal through a set transmission path. RF switches from Pasternack are used in microwave test systems for routing varying RF signals between instruments, allowing multiple tests to be performed at the same time using the same setup. Pasternack carries 3 basic types of RF and microwave switches: PIN diode switches, RF electromechanical relay switches (RF relays) and manual RF switches.
Pasternack's 50 Ohm RF switches are available with SMA, BNC and N connectors, while their 75 Ohm varieties have Type N and BNC connectors only. Pasternack offers many different switch configurations including single-pole-single-throw (SPST) switches, 50 Ohm and 75 Ohm single-pole-double-throw (SPDT) switches, double-pole-double-throw (DPDT) switches, single-pole-three-throw (SP3T) switches, single-pole-four-throw (SP4T) switches, single-pole-six-throw (SP6T) switches, single-pole-eight-throw (SP8T) switches, single-pole-ten-throw (SP10T) switches, A/B coaxial RF relays and transfer switches. Pasternack's broadband RF switches have frequency capabilities ranging from DC to 40 GHz depending on type and style and very low VSWR. Pasternack Enterprises’ RF switch products have a power rating between 0.5 Watts and 2 Watts and a maximum speed threshold between 100 and 250 nanoseconds (nsec).
