Abstract:
An attenuator device having at least two ports, the attenuator to compensate the effect of temperature changes in an electronic circuit, the device comprising:a low temperature co-fired ceramic (LTCC) integrated package including a substrate having a pair of major surfaces; a plurality of thermistors embedded within the substrate, at least one of the thermistors comprising a sheet of thermistor material having a pair of major surfaces and a pair of electrodes formed on and laterally spaced apart by the major surfaces, the thermistor sheet layered with insulating layers and the electrodes on the major surfaces interconnecting the thermistors, the thermistors forming the components of an attenuator in a temperature compensating circuit; and at least three terminals forming the at least two ports, wherein one of the terminals comprises an input electrode connected to one of the thermistors, one of the terminals comprises an output electrode connected to at least one different thermistor, and one of the terminals comprises a common terminal.
