Abstract: 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.

Abstract: 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.

Abstract translation: 一种共面带通滤波器（10），其具有由至少第一和第二串联布置的导电部分（18,19）形成的中心线（15），所述导电部分由间隙（16）分开。 中心段的两侧有谐振器（30,31），用于耦合来自第一和第二段的返回电流。 可以包括导电条或导电平面（270）的导电构件（40,41）分别设置在谐振器和中心线的相对侧上。 带通元件（50,60）可以设置在导电带或平面中以减少或消除寄生通带频率。
