Claim 0:
1. A composite electronic device comprising:
a Printed circuit board, PCB, having a first coefficient of thermal expansion; and
a ceramic electronic device having a second coefficient of thermal expansion different than the first coefficient of thermal expansion the ceramic electronic device; including:
a ceramic waveguide, CWG, device having at least two input/output, I/O, ports; and
a ceramic stripline, CS, device comprising at least one stripline transmission path having at least two I/O ports, the CS device being affixed to the CWG device such that at least one of the I/O ports of the CWG device is eclectically connected to an I/O port of the CS device; and

the bottom surface of the ceramic electronic device comprising:
at least three contact bumps disposed on a periphery of the bottom surface, the contact bumps configured for sliding contact with the printed circuit board, PCB;
an I/O port disposed within an inner portion of the bottom surface; and
at least one ground port disposed on the bottom surface proximal to the I/O port;
the I/O port and the at least one ground port comprising respective solder bumps configured to form fixed mechanical and electrical connections between the composite electronic device and the PCB.
