Abstract: 본 발명은, 소형화, 저 손실과 고 감쇠극을 제공하며, 설계시 유전상수에 따른 설계제한에서 자유롭게 하여 설계공정을 최적화하여 제조단가를 줄일 수 있는 마이크로스트립 교차결합 대역통과필터를 제공한다.
본 발명에 따른 마이크로스트립 교차결합 대역통과필터는, 입력단자와 전계결합되는 입력공진기와 출력단자와 전계결합되는 출력공진기 사이가 자계결합되고, 입력공진기와 출력공진기가 자계결합되는 사이 간격인 교차결합 갭이 형성된다. 또 입력단자 및 출력단자와 복합적인 전계결합되는 교차결합선로가 더 포함된다.
여기서, 교차결합 갭은 통과대역의 상측에 감쇠극 특성을 발생시키는 간격이며, 교차결합 갭의 간격의 변화에 따라 감쇠극의 감쇠주파수가 변화될 수 있다. 또한, 교차결합선로는 통과대역의 상측 및 하측에 감쇠극 특성을 발생시키며, 교차결합선로와 상기 입출력단자와의 간격, 교착결합선로의 길이 및 폭에 따라 감쇠극의 주파수가 변화될 수 있다.

Abstract: A S/N enhancer using the magnetostatic wave signal. The S/N enhancer comprises a balun coupler for dividing an input signal into a first and second signals having the same power, the second signal having the phase difference of 180 degree with respect to the first signal; a saturation magnetostatic wave filter for receiving the first signal output from the balun coupler, converting that into a magnetostatic wave signal, and oppositely converting the magnetostatic wave signal, wherein the power of the magnetostatic wave signal is saturated if the first signal has the power of equal to and more than that of a noise signal; a delay line having the linearity to transmit the second signal output from the balun coupler; and a power synthesizer for synthesizing the respective signals output from the saturation magnetostatic wave filter and the delay line.

Abstract: PURPOSE: A mixed active network model and a packet processing method in an active network model are provided to classify packets into an 'Aflow' packet, a 'non-Aflow' packet, and a 'sigAflow' packet according to the continuity of a packet delivery cycle, so as to actively load resources necessary for performing active packets on an active node. CONSTITUTION: If an optional packet is received to a packet classifier(S200), the packet classifier decides whether a protocol field of a header of the packet is set as active(S202). If not, the packet classifier regards the received packet as a general IP(Internet Protocol) packet(S204), and if set as active, the packet classifier regards the received packet as an active packet(S206). The active packet is provided to a flow classifier(S208). The flow classifier decides whether the packet matches with a demux key field(S210). If so, the flow classifier classifies the packet as an 'Aflow' packet(S212). If the packet does not match with the demux key field, a performance environment block detects a type field of the active packet header(S214). If a detected type value is '0'(S216), the performance environment block classifies the packet as a 'sigAflow' packet(S218). And if the detected type value is '2'(S220), the performance environment block classifies the packet as a 'non-Aflow' packet(S222).

Abstract translation: 目的：提供主动网络模型中的混合主动网络模型和分组处理方法，以根据分组的连续性将分组分类为'Aflow'分组，'非Aflow'分组和'sigAflow'分组 交付周期，从而主动加载在主动节点上执行活动分组所需的资源。 构成：如果可选分组被接收到分组分类器（S200），则分组分类器判定分组的标题的协议字段是否被设置为有效（S202）。 如果不是，则分组分类器将接收到的分组视为普通IP（互联网协议）分组（S204），并且如果设置为激活，则分组分类器将接收到的分组视为活动分组（S206）。 活动分组被提供给流分类器（S208）。 流分类器决定分组是否与解复用密钥字段匹配（S210）。 如果是，则流分类器将分组分类为“Aflow”分组（S212）。 如果分组与解复用密钥字段不匹配，则性能环境块检测活动分组报头的类型字段（S214）。 如果检测到的类型值是'0'（S216），则性能环境块将该分组分类为'sigAflow'分组（S218）。 如果检测到的类型值是'2'（S220），则性能环境块将该分组分类为“非Aflow”分组（S222）。
