JFW model 50PA-1019-XX is our latest programmable attenuator assembly designed for 5G wireless testing. It is an expandable design that can be configured to have up to 16 individually controlled attenuators. The test system has the following features: Operates 100 MHz to 40 GHz 0 to 62 dB by 1 dB step attenuators Up to […]
JFW has added model 50P-2072 2.9mm to our line of TTL controlled programmable attenuators. It operates 100 MHz to 40 GHz with an attenuation range of 0 to 31 dB by 1 dB steps. It is rated for up to +20 dBm (0.1dB compression at +25 dBm) of RF input power. The RF connectors are […]
JFW does offer the ability for buyers to purchase multiple JFW models under a single kit model number. This can reduce your purchase order down to a single line item for repeated buys. Just let our sales department know which models you would like to include in the kit and we will assign a new […]
JFW model 50FHLB-xxx-100 is a 100 Watt fixed attenuator with 50 Ohm impedance. The unit is uni-directional due to its unusually narrow heatsink design. The 100 Watt heatsink is only 2.25 inches in diameter and 9.08 inches in length. The attenuator can be panel mounted using the four 8-32 mounting holes on each end of […]
A new dual channel attenuator assembly, JFW model 50BA-034-127 SMA, has been added to our lineup of benchtop attenuator assemblies featuring manual lever controls. This model contains two solid-state programmable attenuators with attenuation range 0 to 127 dB by 1 dB steps operating 30 MHz to 3 GHz. Each attenuator can be controlled remotely via […]
JFW model 75PD-188 F is a 11-way resistive divider/combiner that covers the frequency range DC-2150 MHz. It has 75 Ohm F female RF connectors. The unit has 12 total ports that are internally connected using a resistive star configuration. This design is ideal for testing 75 Ohm cable equipment that needs to communicate with each […]
If you would prefer to control our USB attenuator or USB RF switch models using Python instead of our standard Windows based GUI test program, JFW does offer a Python library (jfwusb.py). Email our engineering department for the Python library and examples. Python Library Features: Auto-discovery of any JFW USB devices connected to the computer. […]
JFW model 50BA-032-31 SMA is a 4 channel attenuator assembly that covers 0.1-18 GHz. Each channel consists of a solid-state programmable attenuator with attenuation range 0 to 31dB in 1 dB steps. Each attenuator can be controlled individually or as a group. This benchtop attenuator assembly is remotely controlled via Ethernet/RS-232 and manually via momentary […]
