Latest Patents

One of his latest patents is the Asymmetric Dual-Band Combine Filter. This dual-band filter provides a bandpass characteristic over a first predetermined range of frequencies, along with a notch or band-reject characteristic over a second predetermined range of frequencies. In one embodiment, the notch characteristic occurs within the bandpass characteristic, yielding a filter frequency response with two asymmetric passbands separated by a reject band. This design is particularly suited for cellular Band A receive filter applications, but it can be easily adapted for other uses. Appropriate tuning can restore symmetry to the passbands. Another significant patent is for Multichannel Transmitter Combiners Employing Cavities Having Low Output. This multichannel combiner includes multiple input ports for connection to associated transmitters, narrow bandpass filters for each port, and an output port for connection to an antenna system. The output impedance of the filters is selected to be substantially lower than that used in conventional combiners, significantly reducing undesired reactance produced in the combiner over its operating range. The combiner also includes an impedance transformer to match the low output impedance of the filters to the design impedance of the antenna system.
