Abstract
Circuitry includes a voltage-controlled switch having a transmitter input, a receiver input, and an output that connects to one of the transmitter input and the receiver input. Passive components form a low-pass filter that is electrically connected to the transmitter input. The passive components are part of a multilayer ceramic passive module that includes a base body made of superimposed dielectric layers and electrically conductive layers. The voltage-controlled switch is on an upper portion or a lower portion of the base body.
