Abstract
The improved reed relay package provided a 'pseudo' Form C relay that includes two Form A relays with at least one bridge filter element electrically interconnecting the signal outputs thereof to reduce stub capacitance and improve RF performance. As a result, the reed relay package can operate at very high frequencies, such as 18 GHz and higher. Also, vias can be provided through the support substrate to simulate a co-planar waveguide and RF shields profiled with cut-outs to better simulate a 50 ohm impedance environment throughout the path of the signal line.
