Abstract: A heat exchanger and an antenna assembly having the same are described herein that enable a compact antenna design with good thermal management. In one example, a heat exchanger is provided that includes tube-shaped body. A main cooling volume is formed between the top and bottom surfaces proximate to the outside wall. The main cooling volume has an inlet formed through the top surface and an outlet formed through the bottom surface. A return volume is formed adjacent the inside diameter wall and is circumscribed by the main cooling volume. The return volume has an outlet formed through the top surface and an inlet formed through the bottom surface. One or more exterior fins are coupled to an exterior side of the outside wall. A plurality of fins extend into the main cooling volume. A plurality of inner fins extend into a passage from the inside diameter wall.

Abstract: The present invention provides a beamforming antenna (100, 200, 400) comprising a plurality of antenna elements (101, 102, 201, 202, 401, 402, 440), and a signal generator (103, 403) that is configured to generate for each one of the antenna elements (101, 102, 201, 202, 401, 402, 440) a calibration signal (106, 107, 206, 406, 335) for radiation by the respective antenna element (101, 102, 201, 202, 401, 402, 440) and to supply the generated calibration signals (106, 107, 206, 406, 335) to the respective antenna elements (101, 102, 201, 202, 401, 402, 440). Further, the present invention provides a measurement device (330, 430) for measuring properties (336) of a beamforming antenna (100, 200, 400) according to any one of the preceding claims via calibration signals (106, 107, 206, 406, 335) emitted by antenna elements (101, 102, 201, 202, 401, 402, 440) of the beamforming antenna (100, 200, 400), the measurement device (330, 430) comprising a measurement receiver (332) that is configured to receive an incoming signal (334) comprising the calibration signals (106, 107, 206, 406, 335), and a property determination module (333) that is coupled to the measurement receiver (332) and that is configured to determine the properties (336) of the beamforming antenna (100, 200, 400) based on the received calibration signals (106, 107, 206, 406, 335). Further, the present invention provides a respective antenna measurement system (450) and a respective method.

Abstract: A calibration system for calibrating a number of transceivers, each comprising an in-phase signal path and a quadrature signal path in receive direction and/or in transmit direction is disclosed herein. The calibration system includes a calibration signal generator that is configured to generate a predefined calibration signal for every one of the transceivers, a calibration transceiver that is coupled to the calibration signal generator and to the transceivers and that is configured to supply the generated predefined calibration signals each to the respective transceiver during operation of the transceivers, and/or that is configured to receive the predefined calibration signals after they travel through each one of the transceivers during operation of the transceivers, and a calibration unit that is configured to calibrate the in-phase signal paths and the quadrature signal paths of the transceivers during operation of the transceivers based on the calibration signals as they are received by the transceivers or based on the calibration signals as they are received by the calibration transceiver. Further, an antenna system and a calibration method are also described.

Abstract: An electronic device is provided that balances the force applied to temperature control elements such that stress within components of the electronic device can be effectively managed. In one example, an electronic device is provided that includes a printed circuit board (PCB), a chip package, a thermal management system, a thermal spreader, and first and second biasing members. The chip package is mounted to the PCB. The thermal management system and spreader are disposed the opposite of the chip package relative to the PCB. The first biasing member is configured to control a first force sandwiching the chip package between the thermal spreader and the PCB. The second biasing member is configured to control a second force applied by the thermal management system against the thermal spreader. The first force can be adjusted separately from the second force so that total forces applied to the chip package and PCB may be effectively balanced.
