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 […]
JFW model 50MS-426 is a 50 Ohm 8X8 non-blocking matrix switch operating 350-6000MHz. Each input port can be connected to multiple outputs simultaneously. Each output port can be connected to only one input port. It is remotely controlled via Ethernet or RS-232 connection. The IP settings can be manually set via the front panel display. […]
JFW has added a new line of 50 Ohm solid-state RF switches that operate 20MHz to 8.4GHz. These commercially rated models are ideal for constructing low cost RF testbeds for automated testing. The switches are controlled with TTL control lines. The switches can hot switch up to +26dBm with typical isolation of 55dB at 8GHz. […]
The fixed IP address of our Ethernet Test Box is now 104.63.176.50 (tcp port 3001). If you have been testing our your software with our test box, you will have to update to use 104.63.176.50 (port 3001). The test box is running our latest generation Ethernet/Serial firmware. You can make an Ethernet connection to the […]
Our RF Matrix Switch Guide was recently updated. The guide discusses four different types of matrix switch: Blocking Non-blocking Super non-blocking Common highway The goal of the guide is to help engineers pick out the correct type of matrix switch with the necessary functionality. If you need additional help, please email any of our […]
