Patent number: 11765559Abstract: Systems and methods for monitoring passive components of a passive public safety distributed antenna system are provided, including a bi-directional amplifier, a public safety monitor coupled to and in communication with the bi-directional amplifier, and at least one smart node coupled to and in communication with the public safety monitor. The at least one smart node includes a processor configured to monitor signal characteristic information of at least one passive component of the system and transmit the signal characteristic information of the at least one passive component to the public safety monitor. The public safety monitor generates system performance information based on a signal at the bi-directional amplifier and the transmitted signal characteristic information of the at least one passive component from the at least one smart node.Type: GrantFiled: August 23, 2018Date of Patent: September 19, 2023Assignee: MICROLAB/FXR LLCInventors: Luke Getto, Alejandro Pieroni, Phil Chen, Andre Prazeres

Patent number: 7002433Abstract: A high power, TEM mode directional microwave coupler having low loss and expanded bandwidth uses novel thick suspended substrate conductors to provide multi-octave bandwidth performance in a practical package. Each of two center conductors is formed using metal layer deposited onto three surfaces of a thick dielectric substrate. The conductors, which can be edge-coupled or offset-coupled, form a novel structure in which the non-metallized side of the substrate is oriented toward the facing outside vertical walls. This effectively reduces the effect of the package wall on the coupling structure, permitting a smaller, constant-width dimension, which in turn raises the waveguide cut-off frequency. The result is a directional coupler with an extended high frequency performance, with reduced physical size and low loss.Type: GrantFiled: February 14, 2003Date of Patent: February 21, 2006Assignee: Microlab/FXRInventors: Marek E. Antkowiak, Andrzej Sawicki

Patent number: 3944928Abstract: A communication system comprising a transmitter for radiating a carrier frequency signal, which may be modulated, to a data station. The station includes a rectifier for rectifying the received carrier signal to provide energy to the station elements. A data source at the station produces a data signal representative of the information to be transmitted. A harmonic generator produces harmonics of the carrier signal and the harmonic signal is modulated with the data or information signal. An antenna radiates the modulated harmonic signal to a receiver which demodulates the received signal to extract the information therefrom. Thus, a completely self-contained and economic system is provided, since the carrier signal per se supplies the energy to operate the data station.Additionally, the communication system may include a carrier signal having an address encoded therein and the station may comprise an address decoder so that only a selected addressed station will transmit the desired data at any one time.Type: GrantFiled: July 1, 1974Date of Patent: March 16, 1976Assignee: Microlab/FXRInventors: Harry A.
