Abstract:
A RF connector system comprises an RF connector with PCB interface further comprising a housing, a coaxial RF connector interface and a PCB contact section together with a Printed Circuit Board (PCB). A mechanical connection is made by two wing shaped surface mount sections of the housing having a plurality of surface mount studs adapted to match which pads on the PCB. The electrical connection to the PCB is made by an inner conductor and at least one matching block electrically connected to the housing and providing a matched impedance at the PCB, which has a strip line with a ground plane.
Abstract:
A PIM (Passive InterModulation) test bench comprises a first duplexer having a first port connected via a first filter to a third port and a second port connected via a second filter to the third port. The first port is fed by signal sources providing RF signals at a first frequency and at a second frequency. A spectrum analyzer is connected to the second port. A DUT (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 are 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.
Abstract:
A coaxial connector comprises a center conductor and an outer conductor coaxial to the center conductor. The outer conductor has a cylindrical shape with slits forming a plurality of spring loaded contact elements. The connector further has a base for mounting the coaxial connector and an outer housing. To improve passive intermodulation characteristics, the base, the slotted outer conductor and the outer housing are made of one piece.
Abstract:
A low passive intermodulation (PIM) RF rotary switch comprises a plurality of center conductors connected to stationary pads, at least two rotatable pads connected by a rotatable pad bridge. Depending on the switching state at least two stationary pads are in close proximity to at least two rotatable pads, thus generating a RF signal connection between the center conductors via the stationary and rotatable pads.
Abstract:
A coaxial RF test connector comprises an inner conductor and an outer conductor arranged coaxially to a center axis. The outer conductor comprises a groove for holding a circular shaped contact spring. The contact spring comprises a base and a plurality of arc-shaped contact fingers with gaps between the individual contact fingers extending from the base. The base has a larger radius than the contact fingers. The contact fingers have first contact section for contacting the outer conductor of a compatible coaxial connector in a direction radial to the center axis and a second contact section for capacitively coupling to a sidewall of the groove.
