JFW is proud to announce the addition of a new line of 18 GHz step attenuators to our product line. These new 50 Ohm solid-state step attenuators cover 100 MHz to 18 GHz. We offer these attenuators as individual components or as an integrated RF test system with script friendly remote control. Model #50P-2101 SMA […]
Model 50T-605 is a coaxial RF termination rated for 2 Watts RF input power. It can be selected with either 4.3/10 female or 4.3/10 male as the RF connector. It operates at DC-6000 MHz and has maximum VSWR of 1.1:1.
JFW Industries, Inc is now certified to the ISO 9001:2015 standard. Our updated ISO 9001 certificate is available for download. JFW has operated in a certified quality management system since 1995. 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 […]
This application note discusses the challenges of choosing new RF test equipment for wireless testing. Depending on whether you are testing military radios or wireless cellular equipment, there are many different testing configuration options for selection. Picking the right size and configuration for your RF test system is critical. Feel free to email our engineering […]
