Understanding the Bias Networks
Operation
Each bias network includes two bias tees, one for force and one for sense.
The force bias tee includes a capacitor in the RF signal path that functions
as a high- pass filter and DC block. The sense bias tee provides a through
path for DC. Both force and sense tees include resistive- capacitive
oscillation suppression circuitry to help prevent low frequency bias
oscillation of the device under test. Refer to
