The first port is fed by signal sources providing RF signals at first and second frequencies. A spectrum analyzer is connected to the second port. A device under test is connected between said third port and a third port of a second duplexer. Each of the first and second ports of the second duplexer is connected to a PIM optimized load and/or a standard load. The second duplexer is preferably identical to the first duplexer. For minimizing self-intermodulation, at least the first duplexer comprises at least one filter component and a metal housing, the housing further comprises a monolithic metal body and a metal cover capacitively coupled to the body without any galvanic contact.

摘要： A duplex filter includes a block of dielectric material with top, bottom, and side surfaces and first and second spaced-apart sets of through-holes. A pair of outside walls and a center wall extend outwardly from the top surface. A pattern of metallized areas is defined on the top surface of the block including first and second electrodes that extend on the pair of outside walls respectively and third and fourth electrode antennae that extend on the center wall. The block may be two separate blocks coupled together to form an interior layer of metallization separating the first and second sets of through-holes and the center wall separates respective transmit and receive portions of the pattern of metallized areas.

摘要： A multi-cavity RF filter has at least one electrically conductive coupling probe disposed between two resonator cavities. The coupling probe is provided with an ESD protective arrangement such that the coupling probe is electrically connected to a metallic housing of the RF filter only by the ESD protective arrangement. The ESD protective arrangement is configured to provide (i) a low resistance electrical path from the coupling probe to the metallic housing and (ii) a high impedance to RF energy having wavelengths proximate to a center frequency wavelength of the RF filter.

摘要： An improved microwave cavity filter used in cellular communication systems such as base stations is disclosed. The cavity filter has a conductive housing forming a cavity therein and a hollow conductive resonator configured in the cavity with a folded hat shaped upper portion. A tuning screw extends from the top cover of the housing into the top folded hat portion of the hollow resonator to fine tune the resonator. The resonator also may preferably include two different diameter sections providing a first high impedance section with smaller diameter and a second lower impedance section with a larger diameter configured at an upper end of the resonator. This configuration provides a significantly smaller cavity height for a given power handling capability. The resonator is preferably of constant thickness allowing low cost stamping or other forming techniques to be used in forming the resonator.
