    • The invention discloses a dual frequency multiplexer by which a first and second coaxial harmonic oscillator type band pass filters are disposed in a box. The box includes a base body, a cover plate and a cover body. The two coaxial harmonic oscillator type hand pass filters are located on the base body and spaced each other by a metal plate; the multiplexer port, first and second ports are positioned on lateral side of the base body. The blocking capacitors are contained in the coaxial chamber of the two coaxial harmonic oscillator type band pass filters. The cover plate is secured on the base body; the first and second direct current circuits are placed on the cover plate; the low pass filters of the first and second direct current circuits are fixed on an edge of a top surface of the coaxial chamber by means of a support member; the cover body and the base body are fastened with each other. The blocking capacitors each are of distributed parameter capacitor. Utilization of distributed blocking capacitors makes the product of the invention small. Moreover, improvement of the structure of the invention brings effect such as less differential loss, large power capacity, as well as high isolation degree between circuits.

    • The invention discloses a DCS/WCDMA dual frequency multiplexer. On one hand, the multiplexer utilizes distributed parameter type capacitors in place of conventionally used capacitors. On the other hand, within the multiplexer, a direct circuit and a RF circuit are isolated from each other physically. All components including capacitors co-exist together physically. Similarly, the invention further discloses a dual frequency multiplexer with large application range. It also utilizes the distributed parameter type capacitors like the DCS/WCDMA dual frequency multiplexer. Because the invention has redesigned the entire construction of the multiplexer, it results good effects such as small size, less differential loss, large power capacity, as well as high isolation degree between circuits.
    • 本发明公开了一种DCS / WCDMA双频多路复用器。 一方面,多路复用器使用分布式参数型电容器代替常规使用的电容器。 另一方面,在多路复用器内,直接电路和RF电路在物理上彼此隔离。 包括电容器在内的所有组件在物理上共存。 类似地,本发明还公开了具有大应用范围的双频多路复用器。 它还利用分布式参数型电容器,如DCS / WCDMA双频多路复用器。 由于本发明重新设计了多路复用器的整体结构,所以产生了很好的效果,例如尺寸小,差分损耗小,功率容量大,电路隔离度高等优点。

    • Disclosed is a method, a device, such as a mobile station, and an information bearing medium that tangibly embodies a program of machine-readable instructions that are executable by a digital processing apparatus to perform operations to receive data packets. In this case the operations include verifying the correctness of a received data packet; storing a data packet found to have an incorrect TCP layer header checksum and signaling the source of the received data packets and, in response to receiving another instance of a previously received incorrect data packet, verifying the correctness of the received another instance of the data packet and, if correct, using information obtained from verifying the correctness of a header of the received another instance of the data packet to re-verify the correctness of the at least one stored data packet that was previously found to be incorrect. The correctness of the received data packet is preferably verified by use of a PPP layer FCS checksum, an IP layer header checksum and a TCP layer checksum. The data packet headers are preferably compressed by using a V-J header compression technique.
