摘要： A radar detection system that estimates the received pulse frequency of a pulse in a received radar signal using a signal transmit frequency or one that uses frequency agility during a pulse duration. The radar detector system may include a radar detector that receives the radar signal from an antenna or antenna array. The receiver may be channelized, and each channel path may include Gaussian bandpass filter(s) centered at a different frequencies. The system includes an extended range radar detector that receives the signal in the channels and processing logic that processes the detected channel signals to identify the pulse frequency of emitters with or without frequency agility during a pulse duration. The frequency estimates of the pulse are based on calibrated amplitude differences in adjacent channels.

摘要： Various systems may benefit from interfaces for handling multiple types of inputs. For example, a device with a trigger input from an external device may benefit from an isolated logic level trigger that is capable of addressing multiple types and values of voltage. An apparatus can include an input configured to receive an external trigger input signal having a trigger input voltage. The apparatus can also include circuitry configured to automatically adjust the trigger input voltage to a value configured to be compatible with a provided attached system. A working range of the trigger input voltage can exceed a compatible working range of the provided attached system.

摘要： A power combiner/power divider has a disk shaped housing cavity and a housing of electrically conductive material, such as metal. A junction pin is positioned centrally in the power combiner/divider. Additional ports are positioned radially along the periphery of the disk shaped portion. Tapered waveguides may extend from the radially positioned ports to the centrally positioned junction pin. A hollow radial cavity provided in the cavity holds a dielectric insert that may have tapering extensions radiating from a central ring. The ring surrounds the centrally positioned port.

摘要： A circulator may include a first port having a first port impedance matching circuit defining an impedance of the first port, a second port having a second port impedance matching circuit defining an impedance of the second port, and a third port having a third port impedance matching circuit defining an impedance of the third port. In an example embodiment, the impedance of the first port may be provided to match an impedance of a first external circuit, the impedance of the second port may be provided to match an impedance of a second external circuit, and the impedance of the third port may be provided to match an impedance of a third external circuit. The impedance of the third port may be different than the impedance of the first port.

摘要： An electrical contact is provided for mating with a mating contact. The electrical contact includes a base extending a length along a central longitudinal axis, and an arm extending a length outward from the base along the central longitudinal of the base. The arm includes a first mating bump and a second mating bump. The first and second mating bumps have respective first and second mating surfaces. The arm is configured to engage the mating contact at each of the first and second mating surfaces to establish an electrical connection with the mating contact. The first mating surface of the first mating bump is spaced apart along the length of the arm from the second mating surface of the second mating bump.

摘要： A challenge/response system separates a physically unclonable function from the challenge/response. Bits in a challenge are used to qualify random data values. The random data values are permuted to generate a result. The result is used to encrypt a response that is sent in reply to the challenge. Additional permuting mechanisms may be used to further obfuscate the response.

摘要： An RF connector includes a conductive pin for carrying an RF signal. The conductive pin has a first longitudinal end that serves to interface with a male RF connector to receive the RF signal. The pin also includes a second longitudinal end for connecting with a printed circuit board (PCB). The second longitudinal end may be tapered, and the pin may have a groove formed above the tapered end. A housing encircles the conductive pin. The housing is shaped and sized to accept the male RF connector. A grounding element may be positioned on the bottom of the housing. The grounding element is to contact the PCB when the connector is connected to the PCB. The grounding element may be ring-shaped and soldered to the housing or epoxied to the housing.
