  • Page 5: General Information

    General Information The 11612A bias network provides a means of supplying dc bias to the center conductor of a coaxial line of a component or device while blocking the DC bias to the RF input port. This manual contains information required to install, operate, and test the 11612A bias network.
  • Page 6 It is critical that you properly set the power levels before connecting the bias network to the power supply. Failure to do so may result in irreparable damage to the bias coil. Bias coils damaged by overheating are not covered under warranty. 11612A Operating and Service Manual...

    The circuit is a “tee” in which the capacitor in the left arm acts as a DC block/high pass filter. The vertical arm, with its series inductance and shunt capacitance, acts as a low pass filter. Figure 2 Bias Network Schematic Diagram 11612A Operating and Service Manual...
  • Page 9 The following procedure sets the correct power levels for the bias network when you’re using it for pulsed measurements. This procedure applies only to the 11612A option 001 high current bias network and should not be used with the standard 11612A.
