JFW has added three new power divider models to the website that operate 500-8400 MHz. The 2-way, 4-way, and 8-way models are available with SMA female connectors. They are a reactive type design which has low loss and isolation of 18dB typical. This type of reactive power divider/combiner is ideal for signal fan-in or fan-out […]
JFW has added a new DC-40 GHz attenuator to our fixed attenuator lineup. Model 50HFFB-xxx-5/40 is rated for 5 Watts average. It is available with 2.92mm male/female connectors. It is the second model in our HFFB model line: 50HFFB-xxx-5/40 2.9MM | 5 Watts, DC-40GHz 50HFFB-xxx-2/40 2.9MM | 2 Watts, DC-40GHz
JFW has added a new line of RF switch assemblies that operate 20MHz to 8.4GHz to cover the 5G future 8GHz spectrum band. These models are remotely controlled via Ethernet/Serial. The switches can hot switch up to +26dBm with typical isolation of 55dB at 8.4GHz. Switch Assembly Model Numbers: 1P2T model: 50SA-803-XX SMA 1P4T model: […]
JFW model 50HFFA-xxx-50/18 is a 50 Watt attenuator that operates DC-18GHz. It is available with either N or SMA connectors. It is one of several 18 GHz models JFW offers with cylindrical heatsinks: 50 Watt Attenuator | 50HFFA-xxx-50/18 30 Watt Attenuator | 50HFFA-xxx-30/18 25 Watt Attenuator | 50HFFA-xxx-25/18 20 Watt Attenuator | 50HFFA-xxx-20/18 10 Watt […]
JFW has recently added four new models to our website. They are conduction cooled (aka bolt down) type 50 Ohm terminations. The enclosure is flanged with 4 mounting holes so it can be bolted down to a cooling plate or heatsink. The terminations are available with SMA or N type connectors. Model 50T-686: 100 Watts […]
Four new models have been added to the JFW website. These attenuator assemblies operate at 200-7125 MHz with attenuation range 0-95dB by 1dB steps. All of these models feature Ethernet remote control that can be used with scripts for automated testing. 50BA-056-95: 1 attenuator in benchtop chassis 50BA-057-95: 2 attenuators in benchtop chassis […]
By: Paul Pickering When purchasing RF test equipment, such as an RF switch or a programmable attenuator, it’s tempting to concentrate on specifications such as insertion loss, frequency range or VSWR. But implementing a complex testing scheme usually involves integrating multiple pieces of equipment from multiple manufacturers. A customer will often purchase the first piece […]
In order to remain competitive and offer the latest in high-speed services, cellular hardware and Internet-of-Things (IoT) device manufacturers and system operators are moving to higher frequencies now available with Wi-Fi 6E (5.925 GHz to 7.125 GHz) and mid-band 5G (sub-6 GHz). Moreover, these latest devices now operate in a wider variety of network topologies […]
JFW has added two new 75 Ohm matrix switches to our website model listings. One model is “blocking” type and the other is “non-blocking” type. Blocking matrix designs are constructed with RF switches on both halves of the matrix. Non-blocking matrix designs use power dividers on the input half of the matrix and RF switches […]
