Abstract: A radar signal processing system with a self-interference cancelling function includes an analog front end (AFE) processor, an analog to digital converter (ADC), an adaptive interference canceller (AIC), and a digital to analog converter (DAC). The AFE processor receives an original input signal and generates an analog input signal. The ADC converts the analog input signal to a digital input signal. The AIC generates a digital interference signal digital interference signal by performing an adaptive interference cancellation process according to the digital input signal. The DAC converts the digital interference signal to an analog interference signal. Finally, the analog interference signal is fed back to the AFE and cancelled from the original input signal in the AFE processor while performing the front end process, reducing the interference of the static interference from the leaking of a close-by transmitter during the front end process.

Abstract: In a method of manufacturing an electronic package, first grooves are formed on a circuit structure and a second groove is formed in each of the first grooves to allow the circuit structure to become circuit layers. Owing to the second groove is narrower than the first groove, each of the circuit layers has an encircled surface and a notch located on the encircled surface. When a shielding layer is provided to cover an encapsulating body located on the circuit layer, a space of the notch is not covered by the shielding layer such that a portion to be removed of the shielding layer will not remain on the electronic package to become burr after removing the portion to be removed.

Abstract: A package includes a first package component including a semiconductor die, wherein the semiconductor die includes conductive pads, wherein the semiconductor die is surrounded by an encapsulant; an adaptive interconnect structure on the semiconductor die, wherein the adaptive interconnect structure includes conductive lines, wherein each conductive line physically and electrically contacts a respective conductive pad; and first bond pads, wherein each first bond pad physically and electrically contacts a respective conductive line; and a second package component including an interconnect structure, wherein the interconnect structure includes second bond pads, wherein each second bond pad is directly bonded to a respective first bond pad, wherein each second bond pad is laterally offset from a corresponding conductive pad which is electrically coupled to that second bond pad.

Abstract: A new wide-frequency-band spherical antenna structure which comprises a spherical antenna, an insulating sleeve, an impedance-matching element, a fixed disc, a center-needle seat, and a socket member with a high-frequency connector; the impedance-matching element (inductance coil) is to be fitted in the spherical antenna and the socket member; the impedance-matching element and the socket member of the high-frequency connector form an impedance-matching network to provide a nominal capacitance; the structure not only can facilitate the assembling procedures thereof, but also can omit the test and adjustment procedures as required by the conventional antenna; moreover, such an antenna has a small size without affecting the excellent reception efficiency.
