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.
JFW model 50PA-1197 SMA is a 50 Ohm benchtop attenuator assembly operating 200-6000MHz. It contains 24 individually controlled step attenuators with attenuation range 0-95dB x 1dB steps. Each attenuator has two ports that are both cabled to the rear panel. The rear panel has a total of 48 SMA female connectors (i.e. two SMA per […]
JFW model 50MS-404 is an 8 x 8 blocking matrix switch operating DC-18 GHz. It is constructed using electro-mechanical switches on the input half and output half of the matrix. This type of construction results in low insertion loss and high port-to-port isolation. All unused input ports and unused output ports are absorptive (i.e. self-terminating […]
JFW model 75BA-004-95 is a dual channel benchtop attenuator. The 75 Ohm attenuators have attenuation range 0-95dB x 1dB steps and operate 5-2150MHz. The attenuators are solid-state design for long lifetime and repeatability. That makes them perfect for repetitive product testing or lab testing that requires repeatable accuracy. The attenuator comes in a mini-benchtop enclosure. […]
JFW has a new 50 Ohm USB attenuator to help automate your Wi-Fi 6E testing. Model 50P-2111 SMA operates from 200MHz to 8.4Ghz with attenuation range 0 to 95dB by 1dB steps. Test software is provided with the USB attenuator. The test software can control multiple JFW USB attenuators to allow for handover signal fade […]
JFW has two new attenuator assembly models to help automate your Wi-Fi 6E testing. Both models use 0-95dB x 1dB step attenuators that operate 0.2-8.4 GHz. Both models feature Ethernet and Serial remote control with a command set that is script friendly. Model 50PA-1183-XX contains up to 8 attenuators and has a 19 inch rack […]
