50 Ohm Solid-State (Absorptive)

JFW’s online absorptive 50 Ohm solid-state RF switch models are listed in the table below. The term “absorptive switch” means that unused ports are internally terminated (i.e. self-terminating) at an impedance of 50 Ohms. The RF switch specifications are sortable for easy model selection. If you can’t find a model to meet your requirements, please contact JFW at sales@jfwindustries.com. To view our reflective solid-state switch models you will need to jump to our reflective model table.

With our extensive line of solid-state and electro-mechanical RF switch models, JFW has solutions to fit your specific coaxial RF switch applications. Whether you are performing benchtop testing or computer automated testing, JFW’s solid-state coaxial switches have the proven reliability needed for your RF and microwave testing.

Send in a request with a list of your required RF specifications and JFW will design a 50 Ohm solid-state RF switch model that meets your specific requirements.

Common solid-state RF Switch Terminology…

Reflective: Switch ports are high impedance (open) when ports are turned off.

Absorptive: Ports that are turned off are internally terminated with the proper impedance. (i.e. 50 Ohm impedance models are internally terminated with 50 Ohms.)

Self-terminating: This term is used interchangeably with “absorptive”. Ports that are turned off are internally terminated with the proper impedance. (i.e. 50 Ohm impedance models are internally terminated with 50 Ohms.

Hot Switching: The switch changes state while a RF signal is still being applied to the switch.

Cold Switching: No RF signal is applied to the RF switch while the RF switch is changes states.

Switching Speed: Port turning ON = 50% TTL control to 90% of the RF signal. Port turning OFF = 50% TTL control to 10% of the RF signal.

Rise Time: Port turning ON = 10% of the RF signal to 90% of the RF signal.

Fall Time: Port turning OFF = 90% of the RF signal to 10% of the RF signal.
