ABSTRACT:
The present invention describes a switch (10) designed primarily for use in the radio frequency and microwave spectrums. The switch (10) of the present invention uses a lumped element network (16), PIN diodes (18), and capacitive elements (20) to provide isolation in an "open" position wherein the PIN diodes (18) are forward biased. In a "closed" position, wherein the PIN diodes are not forward biased, signals propagate through the switch (10) unhindered because the input impedance of the lumped element network (16) substantially matches the characteristic impedance of transmission line segments (12 and 14) that provide input and output paths to the lumped element network (16).
