Circuit having four sets of terminals arranged in two pairs designed so that there is high loss between the two sets of terminals of a pair when the terminals of the other pair are suitably terminated. Commonly used to couple four-wire circuits to two-wire circuits.
a device that performs all or part of an electronic function by combining and interconnecting several passive and active semiconductor devices into a single package
A microcircuit consisting of elements which are a combination of the film circuit type and the semiconductor circuit type, or a combination of one or both of these types and may include discrete add-on components.
An insulating base material with various combinations of interconnected film conductors, film components, semiconductor die, passive components, and bonding wire which form an electronic circuit.
Circuit that combines two technologies (passive and active or discrete and integrated components) onto one microelectronic circuit. Passive components are usual made by thin film techniques, while active components are made with semiconductor techniques.
A transformer arrangement that permits the transmitted and received signals to be separated and then put back together. Used to connect a 2-wire line to a 4-wire line.
A circuit where passive components (resistors, capacitors) are deposited onto a substrate made of glass, ceramic, or other insulating material. Then the active components (diodes, transistors) are attached to the substrate and connected to the passive components on the substrate with a very fine wire.
