New description: [New technical field] This new type is related to a kind of filter and wave filter, and it is especially related to a kind of miniaturized dual-band pass filter. [Prior Art] Wireless communication is an area that has flourished in recent years. The trend of fine multi-bandwidth of wireless communication transceivers has been developed to provide more (four) nature, and different services can be used through single-multi-mode multi-turn base stations. Both GSM and WCDMA transceiver systems are designed to achieve dual-frequency switching by switching. This type of architecture requires two transceivers operating in different frequency bands, so higher cost, larger circuit area, and more gods are required. The proposed parallel dual-frequency circuit architecture is used to overcome these shortcomings. In the dual-frequency circuit architecture, a single receiver can work in both the 2.4 GHz and 5.2 GHz bands. The low noise amplifier and the data filter are both passbands and passbands at 2.4 GHz and 5.2 GHz. The external signal needs to be effectively suppressed.
