High performance out of Hollow PKG at RF Semiconductor
CDK's original hollow packaging technology creates an ideal air structure for the RF signal around the semiconductor die. Due to this, ultra-low noise HEMT which receives radio waves of satellite broadcasting can amplify waves with high efficiency. With high-throughput manufacturing line, CDK has achieved the shipments of more than 50 billion number in total.
Issue
Semiconductor chip's performance can vary widely in the wireless communication by its surrounding environment even using the same ship. In particular, ultra-low noise HEMT for satellite broadcasting, performance can be deteriorated significantly by molding compound or others around chip and worsen the performance of the entire satellite broadcasting receiving apparatus simultaneously. It could cost much to make improvement.
Solution
Our original hollow packaging technology creates an ideal air structure for the RF signal around wireless communication semiconductor. Thus, for example, in the reception for ultra-low noise HEMT of satellite broadcasting, the semiconductor performance can be pulled out to the fullest. Low noise and high gain can be realized by using the same chip with hollow packaging technology.
