Abstract

"ESTRUTURA DE CIRCUITO COPLANAR PARA SUPRIMIR MODOS ESPúRIOS" Filmes resistivos com perdas (220, 220') e condutores coplanares longitudinalmente se estendendo (206, 210) de uma linha de transmissão de radiofreq³ência são definidos sobre a superfície planar (204) de um substrato isolante (202). Os filmes resistivos (220, 220') podem ser posicionados longe de ou no espaço entre condutores paralelos (206, 210). Os condutores coplanares podem ser configurados como uma linha de fenda coplanar de dois condutores (206, 210) ou como parte de um guia de onda coplanar de três condutores (206, 210, 230). O filme resistivo (338) também pode ser estendido (mar de resistores) através de partes de outra forma não usadas do substrato. Ainda outra concretização provê uma estrutura resistiva coplanar de atenuação de sinal (350) entre um condutor de sinal de coplanar (356) e condutor de terra coplanar (370). A estrutura resistiva coplanar (400, 500) pode compreender um condutor de meandro ou serpentina (510) ou dedos de filme resistivo em forma de pente interdigitalizados (412a, 416)."COPLANAR CIRCUIT STRUCTURE TO SUPPRESS SPORIOUS MODES" Lossy resistive films (220, 220 ') and longitudinally extending coplanar conductors (206, 210) of a radio frequency transmission line are defined on the planar surface (204) of a substrate insulating (202). Resistive films (220, 220 ') can be positioned away from or in the space between parallel conductors (206, 210). Coplanar conductors can be configured as a two-conductor coplanar slit line (206, 210) or as part of a three-conductor coplanar waveguide (206, 210, 230). The resistive film (338) can also be extended (sea of resistors) through otherwise unused parts of the substrate. Yet another embodiment provides a coplanar resistive signal attenuation structure (350) between a coplanar signal conductor (356) and coplanar earth conductor (370). The coplanar resistive structure (400, 500) can comprise a meander or serpentine conductor (510) or interdigitalized comb-shaped resistive film fingers (412a, 416).
