Abstract
A system for switching radio frequency signals from an input side (,FIG.,) to an output side (,) can be used to combine multiple input signals to form a single output and to distribute a single input signal to form multiple outputs. Gain correction amplifiers (,) are employed to adjust the overall gain of a particular column and row of the switch matrix which minimizes the effect of variations in the gain of the amplified switching elements (,) which perform the switching function. Resistive matching units (,FIG.,) provide coupling to and from the amplified switching elements (,) without substantially changing the characteristic impedance of the input and output paths.
