The programmable attenuator models listed in the table are only our online models. JFW has over 2045 different models of programmable attenuators. If you can’t find a model in the table that fits your exact 50 Ohm programmable step attenuator requirement, please contact JFW. We do not charge NRE’s for new programmable step attenuator models. We pride ourselves in the ability to offer custom 50 Ohm programmable step attenuator models with the same pricing and delivery as our catalog programmable step attenuator models. Send in a request with a list of your required RF specifications and JFW will design a 50 Ohm programmable step attenuator model that meets your specific requirements.

Over 20 years ago JFW moved from making just programmable attenuators to also making RF test systems. Since JFW manufactures programmable attenuators, we are able to use our own 50 Ohm programmable attenuators inside of our RF test systems. That allows JFW to design and manufacture custom programmable attenuator test systems with no NRE’s and quick delivery times.

Send us a block diagram of your programmable attenuator assembly and JFW will respond with a ROM quote (rough order of magnitude) quote in 1-2 days. Please visit our test systems web page for more details on all of the RF test systems that JFW offers.
