Patent number: 7388451Abstract: A technique for interconnecting monolithic microwave integrated circuits (MMICS) on a substrate, and a method for fabricating substrate sections that facilitate such interconnection. A MMIC is positioned in a gap in the substrate, on which are formed conventional microwave transmission lines for purposes of MMIC interconnection. On each side of the gap, the substrate is tapered in thickness between the normal substrate thickness and the much smaller thickness of the MMIC. The transmission lines in this transition region are tapered in width as the substrate is tapered in thickness, thereby maintaining uniform transmission line characteristics, particularly the characteristic impedance of the transmission line. Small connector ribbons provide electrical connection between the tapered transmission lines and the MMIC. A method is also disclosed for fabricating multiple substrate sections for use in the structure of the invention.Type: GrantFiled: August 15, 2005Date of Patent: June 17, 2008Assignee: Northrop Grumman CorporationInventors: David J. Brunone, Mark Kintis

Patent number: 6813320Abstract: A receiver (10) for a wireless telecommunications system that provides relatively wideband signal processing of received signals without increased signal distortion so that multiple received signals can be simultaneously processed. The receiver (10) includes a specialized LNA (16), frequency down-converter (18) and ADC (20) to perform the wideband signal processing while maintaining receiver performance. The frequency down-converter (18) employs a suitable mixer (28), BPA (32), attenuator (34), and transformer (36) that are tuned to provide the desired frequency down-conversion and amplitude control over the desired wideband. The down-converter devices are selected depending on the particular performance criteria of the ADC (20). A specialized digital channelizer (22) is included in the receiver (10) that receives the digital signal from the ADC (20), and separates the signals into the multiple channels.Type: GrantFiled: June 28, 2000Date of Patent: November 2, 2004Assignee: Northrop Grumman CorporationInventors: Shimen K.

Patent number: 6498535Abstract: A low noise amplifier (82) for use in a wireless telecommunications system. The amplifier (82) includes an amplifying device (90), such as an FET, and a plurality of oscillation stabilization components monolithically integrated on a common substrate (132). The stabilization components reduce the gain of the amplifying device (90) at high frequencies to prevent high frequency oscillations. The substrate (132) is on the order of 4 mils thick, so that the operation of the stabilization components are predictable at high frequencies.Type: GrantFiled: June 28, 2000Date of Patent: December 24, 2002Assignee: TRW Inc.Inventors: Barry R. Allen, David J. Brunone

Patent number: 6261872Abstract: An advanced electronics package for integrating electronic components of an electronic circuit, such as RF circuits. An important aspect of the invention relates to the simplicity in forming and integrating the electronic components in the package relative to known electronics packages. In one embodiment of the invention, various ceramic preforms are utilized which may be cast with temperature durable electronic components or formed as interconnect channels or feedthroughs. The preforms, in turn, are adapted to be cast into a composite housing, for example, an aluminum silicon carbide (AlSiC) housing. The component preforms may include resistors, capacitors, and inductors. In addition, RF pins as well as DC pads may be cast in the housing. The electronic components are electrically coupled to an interconnect channel or feedthrough.Type: GrantFiled: September 18, 1997Date of Patent: July 17, 2001Assignee: TRW Inc.Inventors: James A. Hathaway, David J. Brunone, Michelle M. Reyes
