Our quality system ensures that JFW manufactures quality RF attenuators and RF switches with a documented manufacturing process and traceable paperwork. Our commitment to […]
Three new 75 Ohm blocking matrix switch models have been added to the JFW website. Model 75MS-029 is a solid-state 2X8 blocking matrix that operates 3-1000MHz. Model 75MS-030 is a solid-state 2X6 blocking matrix that operates 3-1000MHz. Model 75MS-037 is an electro-mechanical 2X12 blocking matrix that operates DC-1700MHz. These 75 Ohm matrix switches can be […]
With the push to 5G by wireless cellular providers, lab benches are now being occupied with a greater number of high frequency fixed attenuators with 2.9 mm (aka 2.92 mm) and 2.4 mm RF connectors. It is important to be able to tell these RF connectors apart because 2.4 mm and 2.9 mm connectors will […]
This application note covers resistive and reactive power divider/combiners. The main goal of this app note is to help customers choose the correct power divider/combiner type for their application. The functionality differences between the two types are discussed with example block diagrams. The block diagram makes it easy to see why resistive divider/combiners are used for […]
This application note discusses the four different construction types for RF matrix switches with pros and cons for each type. Matrix switch types discussed: blocking matrix switches, non-blocking matrix switches, super non-blocking matrix switches, and common highway matrix switches. The functionality of each construction type is discussed with example block diagrams. Please contact our engineering […]
The number one FAQ we receive from customers about our remotely controlled test systems is “How easy is it to connect and control the test system?”. So we setup an Ethernet test box that is accessible 24/7 for engineers around the world to try out. It is running our latest 3.x.x firmware. Connect to the […]
This application note discusses three different testing configurations that can be used to test military radios. The test configurations are: Hub Fan-out, Full Fan-out, and Limited Fan-out. Each configuration has its own testing features and limitations which are discussed. We do provide direct access to our engineering team if you have any questions or want […]
