摘要: Mixer assemblies (100) including mixer cells (110, 110'), baluns (112), quadrature mixers and image reject mixers, etc. The mixer cell may contain CPW strip RF input and slot line strip LO input. LO signal return is provided through a flip-chip (160, 160') mounted to a mixer contact area (140, 140') and the CPW RF input is preferably coupled to the contact area (140, 140') through a distributed or flip-chip mounted capacitor (136, 136'). The use of two mixer cells (110, 110') in novel embodiments of quadrature and image reject mixers is disclosed. CPW to slot line power dividing baluns for use within and without such mixers are also disclosed.

摘要: A coplanar band pass filter (10) having a centerline (15) formed of at least first and second serially arranged conducting segments (18, 19) which are separated by a gap (16). The centered segments are flanked by a resonator (30, 31) for coupling return current from the first and second segments. Conducting members (40, 41) that may include conductive strips or conductive planes (270) are respectively provided on opposing sides of the resonator and centerline. Band pass elements (50, 60) may be provided in the conductive strips or planes to reduce or eliminate spurious pass band frequencies.
