Abstract: An apparatus includes a substrate containing a cavity and a dielectric structure covering at least a portion of the cavity. The cavity is hermetically sealed. The apparatus also may include a launch structure formed on the dielectric structure and outside the hermetically sealed cavity. The launch structure is configured to cause radio frequency (RF) energy flowing in a first direction to enter the hermetically sealed cavity through the dielectric structure in a direction orthogonal to the first direction. Various types of launch structures are disclosed herein.

Abstract: Isolation circuits for digital communications and methods to provide isolation for digital communications are disclosed. An example isolation circuit includes an isolation barrier, a burst encoder in a first circuit, and an edge pattern detector in a second circuit. The example isolation barrier electrically isolates the first circuit from the second circuit. The example burst encoder generates a first pattern in response to receiving a rising edge on an input signal and generates a second pattern in response to receiving a falling edge on the input signal. The example edge pattern detector detects the first pattern or the second pattern received from the burst encoder via the isolation barrier, sets an output signal at a first signal level in response to detecting the first pattern, and sets the output signal at a second signal level in response to detecting the second pattern.

Abstract: A system on a package (SOP) can include a galvanic isolator. The galvanic isolator can include an input stage configured to transmit an input RF signal in response to receiving an input modulated signal. The galvanic isolator can also include a resonant coupler electrically isolated from the input stage by a dielectric. The resonant coupler can be configured to filter the input RF signal and transmit an output RF signal in response to the input RF signal. The galvanic isolator can further include an output stage electrically isolated from the resonant coupler by the dielectric. The output stage can be configured to provide an output modulated signal in response to receiving the output RF signal.
