Patent number: 5424674Abstract: Two wide dynamic range detection circuits are disclosed, which are capable of detecting low-level desired signals in the presence of nearby strong interfering signals. Each circuit includes an attenuator scheme for attenuating the interfering signal while passing the desired signal. The first attenuator scheme uses a YIG filter in combination with an automatic gate arrangement. The second attenuator scheme uses a two-channel arrangement. The first channel uses a chirp-Z processor to derive a pulse-type transform signal in response to the strong interference signal. The second channel includes a YIG filter followed by a programmable notch filter which is controlled by the interference-signal pulse from the first channel. Following the programmable notch filter in the second channel is a chirp-Z processor followed by a gate arrangement wherein the gates are switched "OFF" under control of the interference-signal pulse from the first channel.Type: GrantFiled: November 18, 1992Date of Patent: June 13, 1995Assignee: The United States of America as represented by the Secretary of the ArmyInventors: William J.

Patent number: 5289073Abstract: A low-loss, wideband SAW transducer operating on a piezoelectric substrate with a longitudinal axis of propagation. The SAW transducer has a plurality of tapered interdigital electrodes that are mounted on the substrate transverse to the propagation axis. The electrode widths and spacings are constant along lines parallel to the axis and are tapered in the direction transverse to the axis. An acoustic-wave reflector having a plurality of elongated, tapered discontinuities or reflective fingers is located on the substrate adjacent one end of the transducer. The spacings and widths of the reflective fingers are similar to those of the electrodes, i.e., the finger widths and spacings are tapered in the direction transverse to the axis and are constant along lines parallel to the axis. Because of the taper, the fingers reflect wideband acoustic waves parallel to the axis.Type: GrantFiled: November 9, 1992Date of Patent: February 22, 1994Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Elio A.

Patent number: 5239517Abstract: Disclosed is a coplanar waveguide (CPW) which is connected directly into a balanced SAW transducer" via a tapered coplanar transmission line. Preferably, the CPW transition feeds directly into the "balanced transducer" such that the ground planes of the CPW taper directly into the outer (grounded) bus bars of the SAW transducer and the center conductor of the CPW feeds directly into the "hot" center electrode structure of the SAW transducer. This preferred structure is shown in FIG. 1. This balanced SAW transducer configuration provides better electrical shielding for lower electromagnetic feedthrough suppression and lower spurious signal levels. Moreover, the acoustic wave generated by this "balanced transducer" configuration provides a more uniform acoustic power distribution because the center conductor of the SAW transducer provides a waveguide effect wherein the acoustic energy tends to follow the slow velocity metal structure, thus forming an acoustic waveguide.Type: GrantFiled: August 28, 1992Date of Patent: August 24, 1993Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Elio A.
