LONDON German component manufacturer Epcos AG has bought, for an undisclosed sum said to be in the mid-single digit million Euros, the development activities and patents related to MEMS microphones of Technitrol, Inc. (Philadelphia, PA), opening up a new market for Epcos.
The company will combine Technitrol's s expertise in MEMS microphones with its own competence in manufacturing miniaturized electronic components using its CSMP packaging technology.
The devices and technology being acquired are used in a variety of consumer electronics gear, notably mobile phones and Bluetooth headsets. The market volume of these applications is already in the triple-digit million Euro range, and, Epcos said, increasingly in items such as notebook computers and digital cameras.
Looking ahead, Epcos (Munich, Germany) says it will develop, manufacture and sell MEMS microphones worldwide. In contrast, Technitrol will no longer offer MEMS microphones, which were being sold under the Sonion brand, except "to fulfill certain limited commitments."
The extended Epcos range will cover not only the radio frequency but also the audio frequency range for voice and sound.
The German group is already a leading supplier of RF filters for mobile phone applications , the range comprising discrete filters as well as integrated modules for use in, for example, the transmit and receive systems of mobile phones.
