Abstract: An antenna array system combines the antenna signals from separate antennas (14a,14b) using at least one delay (22) in the RF path of an antenna. In certain embodiments, the antenna array system combines (at 16) the antenna signals in the Radio Frequency (RF) domain before analog-to-digital (A/D) conversion (18), thereby reducing the amount of hardware required when compared to antenna array systems where the antenna signals are combined digitally. The antenna array system may select parameter settings for the antenna array to provide enhanced performance.

Abstract: A semiconductor device comprises a signal pin (1) mounted on a base plate 3 by adhesive (2). Parasitic capacitance exists between the pin (1) and the base plate (3) in the region of adhesive (2) and may deleteriously affect the operation of circuitry in chip (5) connected to pin (1) by a bond wire (4). A bond wire (6) connecting pin (1) to the base plate (3) has an inductance which forms a parallel resonant circuit with the parasitic capacitance, so that, at the resonant frequency, signals on pin (1) at substantially the same frequency pass to or from the chip substantially unattenuated by the parasitic capacitance. Alternatively, the inductances of the signal pin and the bond wires may be such that, at the frequency of signals on the signal pin, an impedance transformation is provided between the input to the signal pin and the end of the first bond wire where it connects to the chip.
