Abstract: A system and apparatus is provided to reduce signal routing, area and signal loss in double-pole, double-throw (DPDT) switch implementations in wireless and millimeter-wave front ends. A staggered arrangement of receivers, transmitters and antenna ports connecting with DPDT switches reduce signal cross-over and allow for compact, low-loss multi-antenna configurations.

Abstract: A transformer includes multiple differential ports and first and second transformer windings. The first transformer winding includes a first transformer half-winding coupled to a first differential port of the differential ports. The first transformer winding also includes a second transformer half-winding coupled to a second differential port of the differential ports. An amplifier system that has a transformer is also provided. The amplifier system includes a first and a second stage amplifier. The first stage amplifier includes a first and a second amplifier. The second stage amplifier includes a third and a fourth amplifier. The transformer is coupled between the first stage amplifier and the second stage amplifier, where the transformer has a primary loop and a secondary loop. The primary loop of the transformer may be configured to receive differential signals of the first amplifier. A method for fabricating a transformer is also provided.

Abstract: A transformer has first and second transformer windings including multiple differential ports. Each of the first and second transformer windings include a first transformer half-winding coupled to a first differential port of the differential ports. Each of the first and second transformer windings also include a second transformer half-winding coupled to a second differential port of the differential ports. Each of the first and second transformer windings is divided symmetrically at a common node to form the respective first and second transformer half-windings. The first transformer half-winding is configured to form one half of an inductance in each of the first and second transformer windings. The second transformer half-winding is configured to form another half of the inductance in each of the first and second transformer windings. The common node of the first transformer winding is configured to receive a supply voltage.
