20140132364 | COMPACT POWER DIVIDER/COMBINER WITH FLEXIBLE OUTPUT SPACING - A compact power divider/combiner with flexible port spacing is disclosed. In an exemplary embodiment, an apparatus includes a three port circuit having first, second, and third ports, and a matching circuit configured to couple the second and third ports to ground. The matching circuit includes a first transmission line connected between a first port and a second port, a second transmission line connected between the first port and a third port, a first matching circuit connected between the second port and a first node, a second matching circuit connected between the first node and the third port, and a third matching circuit connected between the first node and a ground. | 05-15-2014 |
20140152385 | BIDIRECTIONAL MATCHING NETWORK - A bidirectional matching network is disclosed. In an exemplary embodiment, an apparatus includes a first matching circuit connected in a first signal path between a node and a first amplifier, the first matching circuit configured to translate an off-state impedance of the first amplifier to a first translated off-state impedance. The apparatus also includes a second matching circuit connected in a second signal path between the node and a second amplifier. The second matching circuit configured to translate an off-state impedance of the second amplifier to a second translated off-state impedance. The second translated off-state impedance is configured to reduce power loss associated with a first signal flowing in the first signal path and the first translated off-state impedance is configured to reduce power loss associated with a second signal flowing in the second signal path. | 06-05-2014 |
20140152399 | DIGITALLY CONTROLLED PHASE SHIFTER - A digitally controlled phase shifter is disclosed. In an exemplary embodiment, an apparatus includes a first component connected between a first terminal and a node, a second component connected between a second terminal and the node, an impedance selectively connected between the first and second terminals by a first switch, and a second switch to connected between the node and a ground. The apparatus is configured to provide a first amount of phase shift when the first and second switches are in an open position, and a second amount of phase shift when the first and second switches are in a closed position. | 06-05-2014 |
20150207486 | PASSIVE SWITCH-BASED PHASE SHIFTER - Certain aspects of the present disclosure provide apparatus for producing an output signal that may have a phase difference with respect to an input signal. One example phase shifting circuit for producing such an output signal generally includes a transmission line having first and second points, an impedance connected with a node and with a reference voltage level, a first switch connected with the first point of the transmission line and with the node, and a second switch connected with the second point of the transmission line and with the node, wherein a first signal input to the first point of the transmission line has a phase difference with a second signal output from the second point based on one or more properties of the transmission line when the first and second switches are open. | 07-23-2015 |
