Quarter wavelength rf
WebThe mixer cell may contain CPW strip RF input and slot line strip LO input. LO signal return is provided through a flip-chip mounted to a mixer contact area and the CPW RF input is preferably coupled to the contact area through a distributed or flip-chip mounted capacitor. The use of two mixer ... WebIn comparison with conventional quarter-wavelength interdigital resonators, the proposed staircase resonator offers higher compactness and 28% size reduction with wide passband responses. The reported WBPF occupies a small area of 6.5 mm × 8.5 mm with an effective area of just 0.025λ 2 g0.
