Latest Patents

Holzman's latest patents include an innovative architecture for wireless transmission of high-rate optical signals. This apparatus is designed for the wireless transmission of high data rate signals, such as those received from an optical interface, including gigabit fiber channel or SONET. The architecture integrates direct detection of the optical signal with a clock and data recovery circuit, along with a differential signal encoder, which is preferably a differential quadrature phase shift encoder and modulator pair. Additionally, a millimeter wave local oscillator and up conversion chain convert the optical input signal to a microwave carrier. In the reverse direction, the down-converted signal is non-coherently phase detected and processed through synchronized clock and data recovery circuits to recover I and Q channel signals. These recovered signals are then combined and re-timed before being fed back to the optical transceiver.

Another significant patent is the dielectric-filled antenna feed. This invention utilizes a dielectric fill within a waveguide to form an antenna feed. One of the key attributes of the dielectric fill is its ability to reduce aperture size, which in turn increases the beamwidth. Specifically, an RF signal received or transmitted at the end of the waveguide can achieve a wider half-power beamwidth angle than would be possible without the dielectric filling. A portion of the dielectric fill may extend beyond the end of the waveguide to match the waveguide to free space. If the waveguide section is cylindrical, a transformed section made of an annular dielectric ring can be employed to match the feed to a rectangular waveguide.
