The 75 Ohm electro-mechanical RF switch models listed in the table are only our online models. JFW has over 300 different models of 75 Ohm RF switches. If you can't find a model in the table that fits your exact 75 Ohm electro-mechanical RF switch requirement, please contact JFW. We do not charge NRE's for new 75 Ohm RF switch models. We pride ourselves in the ability to offer custom 75 Ohm RF switch models with the same pricing and delivery as our catalog 75 Ohm RF switch models. Send in a request with a list of your required RF specifications and JFW will design a 75 Ohm electro-mechanical RF switch model that meets your specific requirements.

Common Electro-mechanical RF switch terminology...
Normally Open:	With no power applied, the common port is not connected to any of the output ports.
N.O.	Common abbreviation for Normally Open.
Failsafe:	With no power applied, the common port is connected to one of the output ports.
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. 75 Ohm impedance models are internally terminated with 75 Ohms.)
Self-terminating:	This term is used interchangeably with “absorptive”. Ports that are turned off are internally terminated with the proper impedance. (i.e. 75 Ohm impedance models are internally terminated with 75 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.
