  • Switching system utilizing flexible circuit with transmission line for matched impedance connections
    Patent number: 4189676
    Abstract: Switching system for use with a radio transmitter or the like to adapt the same for operation at two different power levels, including a flexible circuit connected to stages of the transmitter and to a switch to control the power level of the signal transmitted. The flexible circuit is very thin so that it can be positioned within the radio housing on the circuit board, and connected to terminals on the board and on the switch. The flexible circuit includes transmission line sections for making matched impedance connections to the transmitter stages for low power loss. The flexible circuit adjusts to take care of tolerances in the position of the terminals to which it is connected.
