A switch selectively provides one of a first input signal at a first frequency and a second input signal at a second frequency to an output terminal with low insertion loss and high isolation between the first and second input signals. The first input signal is received at a first input terminal and the second input signal is received at a second input terminal. A switching element electrically connects the first input terminal and the output terminal to provide the first input signal to the output terminal in a first state and isolates the first input terminal from the output terminal in a second state. A bias line is electrically connected to provide a control signal to the switching element to select between the first state and the second state. An AC coupled transmission line is electrically connected to the second input terminal and electrically connected between the switching element and the output terminal. The control signal is provided through the AC coupled transmission line when the switching element is in the first state to isolate the second input terminal from the output terminal and provide the first input signal to the output terminal. The second input signal is provided DC coupled to the output terminal through the AC coupled transmission line when the switching element is in the second state.

An electrical interconnection includes a flex-circuit having a signal conductor and a shield conductor. A mating surface of the flex-circuit has a signal conductor portion surrounded by a shield conductor portion. The signal conductor portion is electrically coupled to the signal conductor and the shield conductor portion is electrically coupled to the shield conductor.

Flex-circuit shielded connection

A contiguous gasket provides an electromagnetic and environmental seal between the base and lid of a microcircuit housing. The base has a flat surface that allows easy access of tools for assembling electronic components. Channels are cut into a corresponding flat portion of the lid to accommodate the electronic components mounted on the base. High-frequency feedthroughs are brought through sidewall connector features of the base that rise above the assembly surface. Feedthroughs are optionally brought through the flat portion of the base as well. When the microcircuit housing is assembled, the lid compresses the gasket against the base to form an electromagnetic and environmental seal.
