Mix and Match RF Connectors for Fixed Attenuators

Fixed Attenuator with SMA male to N female

Don’t use a fixed attenuator and an adapter, when you can get the fixed attenuator with mixed RF connectors.  The majority of fixed attenuators that JFW manufactures can be specified to have mixed RF connectors.  They don’t have to be just male/female either.  You can specify female/female or male/male.  What is the price difference between 50FHC-030-10 SMA Male/Female (standard model) and 50FHC-030-10 SMA Male/N female?  No price difference!  We stock all of the parts for both models.  It takes the same amount of time to build, test, and QC each model.  Same price.  If you have a specific fixed attenuator requirement, please email our engineering department the details.

3.x.x Firmware Feature Update (3.3.18)

The firmware for our Ethernet/RS-232 models (aka 3.x.x firmware) has been updated.  It is a feature update only.  All changes to 3.x.x firmware are noted on our Firmware Change Log.  For this update, we added increment/decrement functionality into the remote commands:  Set Attenuator (SA), Set All Attenuators (SAA), and Set Block (SB).  Examples of the new functionality can be found in our 3.x.x Firmware Manual.  The examples and command syntax can be viewed in sections 2.3.2, 2.3.4, and 2.3.10 of the manual.  The increment/decrement feature allows you to change the dB setting of a programmable attenuator inside of a test system by specifying only how much dB you want increment/decrement from the attenuator’s current value.  This command allows a user to threshold test a handset by incrementing the dB setting of an attenuator until the handset loses connection with its access point.  Once the handset loses connection, the Read Attenuator command can be used to determine the dB setting at the threshold level.

Introducing Millimeter Wave Attenuation Systems for 5G Development and Test!

50BA-025-62 2.9 MM

These two new series of Ethernet-controlled RF attenuator systems were specifically developed for testing mm-wave and 5G radios in a laboratory environment. An ultra-wide bandwidth of 100 MHz to 40 GHz and attenuation from 0-62dB in 1-dB steps makes both of these systems ideal for receiver sensitivity testing and network emulation of fixed 5G and mobile 5G wireless network components. An easy to use Ethernet/RS-232 interface with front-panel manual control and standard 2.9 MM RF connectors make integration simple as well.
