In one embodiment, a switched amplifier is provided to amplify a data transmission. The switched amplifier may use a control signal that is received via a control signal channel in a transmission cable. Also, the switched amplifier may detect signal power to determine whether the data transmission is received at one of a first port and a second port. Data transmissions via the data transmission channel occur in a first direction and a second direction in a same frequency range in a time division multiplex (TDD) mode. Also, the control signal and data transmission are diverted from the transmission cable that transmits a type of signal different from the control signal and the data transmission. The switched amplifier is controlled based on the control signal or the signal power detected. The amplified signal is diverted in the first direction or the second direction via the data transmission channel back to the transmission cable.

The crack suppressing layer is unadhered to the insulator. The plating layer is adhered to the crack suppressing layer. The crack suppressing layer suppresses an occurrence of a cracking in the plating layer by bending together with the plating layer while being integral and moving with the plating layer in a longitudinal direction of the cable.

An assembly for connecting controlled-impedance cables to a PCB using a crescent-shaped connector that can be located much closer to the unit under test than those of the prior art. On the PCB, equal-length signal traces run from UUT contacts to signal pads that form an arc. All signal pads are surrounded by a ground land. The connector has an anchor block for permanently or removably securing the cables. The connector uses skewed coil contacts held within an electrically conductive plate. The signal contacts are captured in signal through apertures within insulating plugs in the plate. The ground contacts are captured in a ground through apertures. Each signal contact is electrically connected to a cable signal conductor and the ground contacts are electrically connected to the anchor block or ferrule. The connector is shaped so that the signal contacts trace an arc, so that they align with the signal pads.
