摘要： An integrated circuit is formed from a first layer of conductive material (30) which is separated from a second layer of conductive material (39) by a layer of dielectric material (36). The first layer of conductive material (30) is patterned to form a first plate (32, 59) of a capacitor (22, 50, 62, 72). An electrical interconnect (33, 63) is formed within the first plate (32, 59), respectively. A via (37) is formed in the layer of dielectric material (36). A second layer of conductive material (39) is patterned to form a second plate (42, 56, 66, 76) of the capacitor (22, 50, 62, 72) and a planar spiral inductor (21, 51, 61, 71). The planar spiral inductor (21, 51, 61, 71) is surrounded by the second plate (42, 56, 66, 76) of the capacitor (22, 50, 62, 72).

摘要： A broadband 180 degree hybrid having lumped or semi-lumped elements is comprised of a network of low and high pass filters. A 180 degree phase differential is obtained by splitting an input signal from a first input. A first portion of the split signal is passed through a low pass filter and a second portion is passed through a high pass filter. The phase differential is maintained at 180 degrees. A zero (0) degree phase differential is obtained by splitting an input signal from a second input and passing both portions through a pair of low pass filters or through a pair of high pass filters.

摘要： A signal mixing apparatus comprising first and second four port signal splitting/combining networks having no relative phase shift between three ports and 180.degree. of phase shift between the remaining ports, coupled to a four port mixer element. The mixer element has two ports coupled to the first signal splitter/combiner network and having another two ports coupled to the second splitter/combiner, RF and LO signals input to the first splitter/combiner do not appear at the IF output from the second splitter/combiner or vice versa. The RF/IF signals cancel and the LO signal is trapped by a resonant circuit within the mixer. The RF and IF frequency bands may overlap.

摘要： A mixer separates IF components IF1, IF2 of the same frequency which are images of different frequency RF signals RF1, RF2 beating with a given LO signal. The LO signal is applied to a FET active power divider and applied to the drains of a pair of balanced FET mixing elements. The FETs for the active power divider are built from the same device structure as the FETs for the mixing elements sharing drain nodes. The RF signals are passed through a quadrature phase shifter and applied to the gates of the FET mixing elements. The mixed signals appear at the drains of FET mixing elements are applied to opposing ports of a second quadrature hybrid at whose output ports the separated IF output signals IF1, IF2 appear.

摘要： High and low pass filters are coupled to a power divider to create a multi-phase hybrid. The high and low pass filters, and the power divider, are all lumped element for compatibility with MMIC circuitry. The power divider may output, to the high and low pass filters, signals having equal or unequal amplitudes. Similiarly, the high and low pass filters may output signals having equal or unequal phases.
