Abstract:
An electrical connector assembly or cable assembly that carries a combination of radio frequency signals, high speed digital communication signals, and direct current DC power signals is disclosed. The electrical connector assembly exhibits environmental protection. Other features include providing blind mate connection that may be used in a radio transport or fiber transport repeater system for a wireless network.
Abstract:
A modular design repeater platform that allows unique deployment configurations and rapid upgrading, and modifications to a deployed system in a wireless or fiber optic network system is disclosed. The platforms include fiber transport and radio transport systems. The system includes a base unit coupled to one or more RF modules. The components employ a flange—recess design and pedestal mounts to securely couple the components together.
Abstract:
Embodiments provide a novel fabrication method and structure for reducing structural weight in radio frequency cavity filters and novel filter structure. The novel filter structure is fabricated by electroplating the required structure over a mold. The electrodeposited composite layer may be formed by several layers of metal or metal alloys with compensating thermal expansion coefficients. The first or the top layer is a high conductivity material or compound such as silver having a thickness of several times the skin-depth at the intended frequency of operation. The top layer provides the vital low loss performance and high Q-factor required for such filter structures while the subsequent compound layers provide the mechanical strength.
Abstract:
A compact luminaire which includes a housing, a ballast, and a first and second electrical component. The housing has a back and a perimeter wall which extends generally perpendicularly from the back. The perimeter wall has a top wall portion, a bottom wall portion disposed in a downward direction with respect to the top wall portion and sidewall portions connecting the top wall portion and the bottom wall portion. The ballast is mounted to the back adjacent the bottom wall portion and is substantially equidistant to the side wall portions and the first and second electrical components are mounted to the housing on opposite sides of the ballast in a balanced fashion.
