An edge launch radio frequency (RF) signal connector includes ground contact tabs that have radially extending arms. The arms cover a gap between a substrate, such as a circuit board, and the connector to reduce the RF ground path between the RF reference ground and a signal pin supported by the connector. The arms extend radially inwardly from the protruding ground contact tabs toward a central support aperture that supports the signal pin. The arms and the ground contact tabs are formed integrally with the main connector body as one piece. The arms and the ground contact tabs may be planar in shape such that the arms and the ground contact tabs lie flush on the substrate when the connector is arranged over the edge of the substrate.

Methods and apparatus for generating a target signal with desired phase shift information. In embodiments, a system receives an input target signal having a first frequency and combines the input target signal with an oscillator signal to generate a first output signal having a second frequency. The oscillator signal is generated using a digital component that imparts phase-shift information into the oscillator signal. The first output signal is combined with a fixed frequency oscillator signal to generate a second output signal corresponding to a signal reflected from a target.

An isothermal terminator system is provided. The isothermal terminator includes a waveguide formed to define a propagation channel through which electro-magnetic (EM) radiation is directed and a terminator including a body having an exterior surface and an interior surface opposite the exterior surface. The terminator is disposed in the propagation channel such that the EM radiation is incident on the exterior surface to raise a temperature of the body. The body is substantially isothermal with the EM radiation incident on the exterior surface.
