LG Innotek has developed an ultra-small Bluetooth RF module.

– Suitable for slim-type 4.5×3.2×1.2mm cellular phones.
– Capable of making hands-free phone calls without burdensome cables.
– Provide phone makers greater leeway in designing, by integrating several parts into a single module.

Fast-emerging as a new power in the Bluetooth market, LG Innotek (CEO: Young-Ho Hur, www.lginnotek.com) has successfully developed Class 2, an ultra-small Bluetooth RF module so that users could make hands-free phone calls.

The Class 2 developed by LG Innotek has a much-reduced size (5.0×4.0×1.4 mm), smaller by almost 40% when compared to existing Bluetooth RF modules. It is reported that the smaller module is the right product required by slim-type Bluetooth cellular phone makers.

By combining several core cell phone parts like the filter, capacitor, and inductor into one module, the Class 2’s design effectively simplifies the manufacturing process for cellular phone makers. In addition, its ultra-small size provides phone makers greater leeway in designing.

To develop Class 2, LG Innotek adopted its newest and top-notch Low- Temperature Co-fired Ceramic Substrate (LTCC) technology. This state-of-the- art technology has made it possible to develop slimmest and smallest mobile phones by giving substrates high density, extreme slimness, and reduced dimensions.

This RF module is a core component for Bluetooth headsets, and guarantees wireless data and sound communication within a 10-meter distance. Currently, LG Innotek mass produces more than 2 million Bluetooth modules a month.

According to recent research findings by the LG Innotek laboratory, “This newly developed Class 2 is an ultra-small module with integrated functions, making it a very attractive product to cellular phone makers, as well as to a new generation of customers who prefer having Bluetooth-capable cellular phones.”
