Abstract:
An RF assembly ( ) operating at a predetermined wavelength of and having a ground-plane interface ( ) between first and second components ( ) is presented. A bond wire ( ) couples the components ( ) along a bond-wire directrix ( ). The components ( ) have grounding members ( ) establishing substantially coplanar ground planes ( ). The grounding members ( ) are coupled together so as to create a semi-cylindrical slot ( ) having an opening ( ) substantially coincident with the ground planes ( ). The slot has an axis ( ) proximate the bond-wire directrix ( ), and a radius ( ) substantially equal to /2. The slot axis ( ) and the bond-wire directrix ( ) are located within a plane ( ) substantially perpendicular to the ground planes ( ).
High Frequency Gallium Arsenide Mmic Die Coating Method

Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H01L 2156
US Classification:
438127, 438780, 427 96
Abstract:
A moisture resistant conformal coating ( ) effectively protects high frequency circuits such as gallium arsenide MMICs from humidity and environmental contamination without the performance degradation inherent in conventionally applied conformal coatings. The conformal coating preferably comprises an organic polymer, such as silicone, applied to the MMIC die in a substantially uniform thickness of less than 0. 002 inches, preferably of less than 0. 0015 inches. This is accomplished by applying the organic polymer directly to the surface of the die ( ) in a mixture containing the solid organic polymer diluted with a low surface tension solvent, such as a volatile methyl siloxane.

Abstract:
An electromagnetic baffle arrangement includes a lid ( ) having a trough or air gap ( ) in the side walls of each cavity ( ) of lid ( ). Conductive strips ( ) are applied to a layer of printed circuit board ( ) and each of the legs ( ) of lid ( ). Optionally, to eliminate circulation of electromagnetic signals within air gap ( ) a grounded bolt ( ) may be inserted aperiodically.
Broad Band Microwave Biasing Networks Suitable For Being Provided In Monolithic Integrated Circuit Form

Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H01P 122 H01P 115
US Classification:
333 81A
Abstract:
Inductorless bias networks include a bias circuit having a bias return path which is coupled to and biases a variable impedance device in a relatively nonconductive state. Another bias circuit including a FET renders the variable impedance device relatively conductive in response to control signals so that one port is coupled to another port, for instance.

Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H05B 660
US Classification:
257659
Abstract:
An electrostatic RF absorbant circuit carrier assembly (200) is described as having a plastic support structure (100) which consists of an integrally fashioned base (180) and surrounding sidewalls (170) which together form an internal cavity (185). A plurality of conductor paths (125,165) are disposed within the cavity (185). The assembly (200) is completed by a polymeric cover (110) having a surface integrally fashioned to comprise wall members (145) for making contact with conductive paths (165) within the cavity (185). In order to facilitate RF isolation and electrostatic dissipation, the cover (110) is layered with a surface material comprising: a thermosetting matrix system; a non-conductive RF absorbing filler comprising 25 to 87 percent by weight loading of the thermosetting matrix system; and a conductive filler comprising 1 to 4 percent by weight loading of the thermosetting matrix system and the RF absorbing filler.

H01P 1100
US Classification:
29600
Abstract:
A method (60) for molding (67) a component (73) including a free floating insert (11). The method includes steps of providing an insert (11) including one or more weakened regions (23) coupled to a removable leader (20) and molding (67) a moldable compound (25) about the insert (11) and a portion of the removable leader (20). The method (60) further includes a step of pulling (69) on the removable leader (20) to fracture the weakened regions (23) and thereby detach the removable leader (20) from a molded component (73) including the insert (11) therein. The molding step (67) desirably includes a step of injection molding (67) a thermoplastic material (25) about the insert (11) and the portion of the removable leader (20).
Molded Waveguide Feed And Method For Manufacturing Same

Motorola, Inc. - Schaumburg IL
International Classification:
H01P 510
US Classification:
333 26
Abstract:
A waveguide feed is fabricated by first creating a lead frame (10) from a piece of conductive material. The lead frame (10) is shaped by bending arms (22) and probe portions (18) on the lead frame (10) into a desired shape. The lead frame (10) is then placed in a mold and dielectric molding material is added around relevant portions of the lead frame (10). After the dielectric molding material has solidified, excess molding material and extraneous portions of the lead frame (10) are removed from the molded feed assembly. The assembly can then be connectorized and inserted into a waveguide.
