Abstract: A radio-frequency (RF) apparatus includes a wideband receive (RX) impedance matching circuit to provide a received differential RF signal to RF receive circuitry. The wideband RX impedance matching circuit includes first and second inductors to receive the differential RF signal. The wideband RX impedance matching circuit further includes a third inductor coupled across an input o the RF receive circuitry. The third inductor performs the functionality of a capacitor having a negative capacitance value.

Abstract: An apparatus includes a first antenna coupled to a first radio frequency (RF) circuit to receive or transmit RF signals, and a second antenna coupled to a second RF circuit to receive or transmit RF signals. The apparatus further includes a first RF current blocker disposed between the first and second antennas, and a second RF current blocker disposed between the first and second antennas. The first and second RF current blockers increase isolation between the first and second antennas.

Abstract: A system and method for characterizing the performance of an antenna array in a locator device is disclosed. The system comprises a chamber having a locator device and a beacon device. The beacon device is disposed on a rail so as to move in a predictable path while emitting the direction detecting signal. A controller is used to move the beacon device and record its actual position. Phase or direction information collected from the locator device is then supplied to the controller. The controller then compares the actual position to the information received from the locator device and provides this comparison to the user. The path of the rail may allow elevation angles from 0° to 90°. Further, the locator device may rotate, allowing azimuth angles from 0° to at least 180°.

Abstract: An electromagnetic pulse detector in an integrated circuit includes one or more peak hold circuits coupled to one or more traces in the integrated circuit and configured to asynchronously detect voltage spike(s) on the one or more traces and store voltage value(s) corresponding to the voltage spike(s). One or more comparator circuits are coupled to the peak hold circuits to compare the voltage values corresponding to the voltage spikes to one or more threshold voltage values. Storage locations are coupled to the comparator circuits to store indications of the voltage spike(s) being greater than the threshold voltage value to thereby indicate detection of an electromagnetic pulse.
