Device Info and Phased Array Construction
This Variable Delay Line kit can be used to build 2–element wideband receiving phased array with
closely spaced active antenna elements. The signal from one the elements is delayed with…

Schematic diagram of ground connections of different parts of the phased array system with VDL-1 device. This is an important stage in array mounting in order to achieve proper performance…
DC voltage distribution requirements in VDL-1 system with AAA-1C amplifiers
We found out that VDL-1 might have a problem when model AAA-1C active antenna amplifiers are used with it. These models are using optocouplers in the relay control lines in order improve the isolation from strong RF signals induced from high power amplifires (above 1 KW).
