RF and Baseband Techniques for Software Defined Radio

The general structure of a passive broadband 90 splitter network, based upon an all-pass filter configuration, is shown in Figure A.1. Its transfer function is of the form:
where the total network complexity of both the N and P networks is n. The values for for the N and P networks are tabulated in Tables A.1 to A.8. The values in these tables are normalised such that:
