Patent number: 6604949Abstract: The present invention incorporates a hermetic glass bead 206 and a grounding lip 208 into an outer conductor insert 216 to form a microwave coax connector 201. The glass bead 206 forms both the hermetic seal and the support for the coax center conductor pin 214. The outer conductor insert 216 of the coax connector 201 includes the ground lip 208 to provide a short ground path for the connection to a microstrip substrate 10 provided on a carrier 12 in a housing 2. The coax connector 201 is soldered into a cavity 235 in the housing 2 to assure a short ground path between the coax connector 201 and the carrier 12. There is no need for soldering a separate glass bead into the housing 2, which at these high frequencies, is very difficult due to the small size of the glass bead.Type: GrantFiled: March 6, 2001Date of Patent: August 12, 2003Assignee: Anritsu CompanyInventor: William Oldfield

Patent number: 6593829Abstract: A dot termination comprising a disk of thin film resistive material connects a transmission line on a substrate to a DC ground plane in a manner to provide broadband high frequency performance. The dot termination connects to DC ground connections spaced about the perimeter of the disk. Each DC connector includes a ground via passing through the substrate to the ground plane. A metal trace is used for each DC connection, the trace connecting a respective via with the perimeter of the disk. Each metal trace can include a resistive portion connected to the dot region and a metal trace portion connecting the trace to the via. A resistive extension tongue of the disk connects the disk to a transmission line trace.Type: GrantFiled: September 6, 2001Date of Patent: July 15, 2003Assignee: Anritsu CompanyInventors: William Oldfield, Karam Noujeim

Publication number: 20030048146Abstract: A dot termination composed of a circular thin film resistive material connects a transmission line to a DC ground plane in a manner to provide a broadband high frequency performance. The termination uses resistive traces provided around the perimeter of the dot with vias connecting the traces to ground to provide multiple DC paths to ground. The use of these multiple DC paths enhances the high frequency performance of the dot termination, and maintains a desired impedance. The dot termination can be used in a shunt configuration with an optical modulator to provide broadband voltage biasing for the optical modulator. To maximize the biasing voltage, a DC blocking capacitor is placed between the dot termination and ground. Biasing current can be applied between the dot termination and the blocking capacitor to maximize performance.Type: ApplicationFiled: September 6, 2001Publication date: March 13, 2003Inventors: William Oldfield, Karam Noujeim
