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 […]
Test up to 8 radios at one time with isolation between radios. JFW model 50PA-1205 is our widest bandwidth 8X1 LC handover test system test to date. It operates 30-6000MHz. It consists of eight programmable attenuators (0-95dB x 1dB step) that connect to an 8-Way splitter/combiner (see block diagram). The insertion loss paths are from the COM of […]
Model 75PA-123-xx is a 75 Ohm attenuator assembly is available with 1 to 16 attenuators. It covers 5-2150 MHz with 0-63dB x 1dB step attenuation range. Perfect for RF testing of 75 Ohm cable TV equipment. It is remotely controlled via Ethernet or Serial connections. The attenuators can be controlled individually or in groups. The […]
This application note examines the advantages of using VSWR mismatched loads when testing RF amplifiers. The value of testing with mismatch terminations By: Murray Slovick Mismatch loads can be used to test amplifiers and help characterize their performance under conditions that might occur in the field. To do so, a mismatch load (or mismatch termination) […]
OTA vs. Coaxial Interconnect Testing JFW’s newest white paper explores the advantages and disadvantages of both Over-The-Air testing and more traditional testing methods using coaxial interconnects in 5G wireless laboratories. Click here to download the article.
