1. An electronics apparatus comprising:
a first substrate including a first surface and a second surface;
a first switch connected to a second switch and soldered in series with the first switch on the first surface of the first substrate creating an electrical connection to allow high frequency switching between the first switch and the second switch;
insulation including a first surface attached to the second surface of the first substrate; and
a second substrate having a pocket of low permittivity material located between the first switch and the second switch on a second surface of the insulation, the second surface of the insulation being opposite to the first surface of the insulation where the first switch and the second switch are located.
