Test Systems

JFW manufactures a variety of RF test systems.  We can integrate RF switches, step attenuators, and other various RF components into remotely controlled RF sub systems.

The Ethernet/Serial models run our latest generation 3.x.x firmware that features easy to use ASCII formatted commands.

    We can package any of our solid-state or electro-mechanical attenuators into a remotely controlled attenuator assembly.  The Ethernet/Serial models run our latest generation 3.x.x firmware that features easy to use ASCII formatted commands.

    50 Ohm Models with Keypad

    50 Ohm Models with Manual Levers

    • 19 inch Rack:  use levers to manually control attenuators
    • Benchtop:  use levers to manually control attenuators

    75 Ohm Models

  • Handover Test Systems

    Handover Test Systems (43)

    Handover Test Systems for Cellular Testing

    Family of handover test systems designed for handset-to-network handover testing. Internal step attenuators allow the RF signal between the network access points and the handsets to be dynamically faded up/down.  The Ethernet/Serial models run our latest generation 3.x.x firmware that features easy to use ASCII formatted commands.
    • Full fan-out models provide the greatest testing flexibility with individually controlled step attenuator on every RF path thru the matrix.
    • Limited fan-out models use a common highway configuration which reduces the number of internal paths and the number of attenuators.
    • Manual handover models use manually controlled attenuators for simple benchtop testing.
  • Matrix Switches

    Matrix Switches

    JFW offers blocking and non-blocking matrix switches.  They are available with 50 Ohm or 75 Ohm impedance.  The Ethernet/Serial models run our latest generation 3.x.x firmware that features easy to use ASCII formatted commands.  Our RF Matrix Guide steps through the advantages for each matrix type.

    Blocking Matrix Switch:

    • Constructed with RF switches on both halves of the matrix
    • An output port can be connected to only one input port
    • The blocking configuration offers low insertion loss and high port-to-port isolation

    Non-Blocking Matrix Switch:

    • Constructed with power dividers on input ports and RF switches on output ports
    • An input port can be connected to multiple output ports simultaneously
    • The non-blocking configuration offers additional active RF paths but has higher thru loss than blocking design.

  • Transceiver Testing

    Transceiver Testing (30)

    Transceiver Test System for Radio-to-Radio Testing with Full Fan-out DesignTransceiver Test Systems for Radio Testing

    Family of RF test systems designed for transceiver testing.  Designed for radio-to-radio testing in a closed mesh network.  Step attenuators allow you to dynamically fade up/down the RF signal between radios.  These Ethernet/Serial models run our latest generation 3.x.x firmware that features easy to use ASCII formatted remote commands.
