Full Fan-out Handover Test Systems for Cellular Testing
Whether you are fading multiple base station signals to a handset or testing multiple communication standards with wireless devices, JFW has a handover test system to help automate your RF testing.
JFW’s full fan-out handover test systems are a type of matrix switch that is constructed with power divider/combiners on both halves of the matrix with programmable attenuators in between. There is an individually controlled programmable attenuator on every RF path through the matrix. This type of construction allows every input signal to be available simultaneously to every output port at differently attenuated signal levels.

Full Fan-out Handover Test System Example
The below block diagrams show examples of a full fan-out 4 X 2 handover test system. Each path through the test system has its own individually controlled programmable attenuator. This configuration allows for each input signal to be simultaneously available to each output port at differently attenuated signal levels.
The isolation between output ports is determined by summing the isolation of the input power divider/combiner (typically 20dB for reactive type dividers) with the attenuation setting of the programmable attenuators connected to the same input port. That makes it important to keep programmable attenuators on unused paths at their maximum attenuation setting in order to maximize system isolation.
Block Diagram #1
This block diagram illustrates the construction of the full fan-out 4 x 2 handover test system. It shows all of the connectivity between the input ports and the output ports. This design allows the RF signal on input #1 to be simultaneously available to both outputs at different signal levels.
Block Diagram #2
This block diagram shows one possible setting of a full fan-out 4 x 2 handover test system. There are four input signals (red, blue, green, purple). The 1 x 2 power divider/combiners split up the input signals to both output ports. The 1 x 4 divider/combiners sum up all of the input signals for each output port.
Attenuator #1 sets f1 at 0dB of attenuation for Output #1. Attenuator #2 sets f2 at 127dB of attenuation for Output #2. The RF signal on input port #1 is simultaneously available to both output ports at different signal levels.
Block Diagram #3
This block diagram shows another possible setting of a full fan-out 4 x 2 handover test system. The 1 x 2 power divider/combiners split up the input signals to both output ports. The 1 x 4 divider/combiners sum up all of the input signals for each output port.
For this example the user on output port #2 has turned off all of the input signals. The user does this by setting all of the programmable attenuators connected to output #2 to their maximum attenuation setting (i.e. 127dB). The programmable attenuators connected to output port #1 are set to various attenuation settings (i.e. 0dB, 3dB, 6dB, 9dB).
