18 GHz Step Attenuators w/ TTL, USB, or Ethernet Controls

18GHz Step Attenuators

JFW is proud to announce the addition of a new line of 18 GHz step attenuators to our product line.  These new 50 Ohm solid-state step attenuators cover 100 MHz to 18 GHz with an attenuation range of 0-31 dB by 1dB steps.  The attenuators can handle up to +20 dBm of RF input power.  We offer these attenuators as individual components or as an integrated RF test system.

Model #50P-2061
TTL controlled step attenuator, 0.1-18 GHz, 0-30 x 1dB steps
Model #50P-2068
USB controlled step attenuator, 0.1-18 GHz, 0-30 x 1dB steps
Model #50BA-030-31
Ethernet attenuator assembly with (1) step attenuator, 0.1-18 GHz, 0-30 x 1dB steps
Model #50BA-031-31
Ethernet attenuator assembly with (2) step attenuators, 0.1-18 GHz, 0-30 x 1dB steps
Model #50BA-032-31
Ethernet attenuator assembly with (4) step attenuators, 0.1-18 GHz, 0-30 x 1dB steps

USB Programmable Attenuators to 3 GHz w/ 0.25 & 0.5 dB steps

USB Programmable Attenuators

Now available from JFW:  USB Programmable Attenuators with 0.25 dB & 0.5 dB step size up to 3 GHz. The majority of programmable attenuators available have 1 dB steps.  However, for some applications, such as satellite communication testing, smaller step sizes can be beneficial.  For those cases, these three models can provide that capability.

New Models

  • 50P-2058 has 0.25 dB steps up to 31.75 dB.
  • 50P-2042 has 0.5 dB steps to 63.5 dB.
  • 50P-2055 goes all the way to 95.5 dB in 0.5 dB steps.

All three attenuators are controlled and powered through a Mini-B USB connector.  A USB hub can be used to simultaneously control multiple attenuators.  Included with each step attenuator is our Windows-based GUI software for easy attenuation control of a single or multiple attenuators.

Dual Rotary Attenuator for LTE Band 42 Testing

Dual Rotary Attenuator

JFW is excited to announce a new dual rotary attenuator, 50DR-141, that covers LTE Band 42. It functions from DC up to 3600 MHz. This attenuator handles up to 2 Watts of RF power. The maximum attenuation is 40 dB in 1 dB increments. The 50DR-141 has mounting holes in the front plate for easy mounting on panels for instrumentation applications. RF connector options include SMA or N.

In addition, the 50DR-141 can also be configured on 19″ Rack Panels, L-Brackets or Benchtop enclosures for use in test racks or lab environments.

Matrix Switch for use with 75 Ohm Network Analyzers

75 Ohm Matrix Switch

Three new 75 Ohm blocking matrix switch models have been added to the JFW website.  Model 75MS-029 is a solid-state 2X8 blocking matrix that operates 3-1000MHz.  Model 75MS-030 is a solid-state 2X6 blocking matrix that operates 3-1000MHz.  Model 75MS-037 is an electro-mechanical 2X12 blocking matrix that operates DC-1700MHz.  These 75 Ohm matrix switches can be used to fan-out connections from a 2-port 75 Ohm network analyzer to allow for automated multi-port 75 Ohm testing.  Connecting the 2X12 matrix in series with a 2-port network analyzer, creates a twelve port test set.  For all three models, the unused output ports are self-terminating at 75 Ohm impedance to keep the DUT properly impedance matched at all times.  All three models are remotely controlled via serial or TCP/IP connections.  The remote command set consists of simple ASCII formatted commands.  The remote command set for our 3.x.x firmware is available for download.  If you have any technical questions about these 75 Ohm matrix switches, please contact our engineering department for assistance.
