In contrast to theory, practical realizations of micro-strip-to-slotline and CPW-to-slotline baluns do not demonstrate characteristics of an all-pass network.
Under some circumstances, the performance of the lossy impedance match can be improved by including a capacitor from the input to the node between the inductor and the resistor that forms an all-pass network.
A quadrature filter using active all-pass networks is an attractive solution since the filter poles can be adjusted independently and each adjustment requires a change in only one component.
It is important that all four blocks be designed completely symmetrical except for two variable GaAs MESFETs used as variable resistors in the two all-pass networks of the quadrature power splitter.
