DEVELOPMENT of DC POWER DECOUPLING DEVICEs in the Quasi-Millimeter-Wave Band

FEB/25/2005

Along with the recent development of quasi-millimeter-wave communications, there is an increasing need for wider band isolation. This paper reports the successful development of a wideband filter with 20 dB up to 16.7 GHz and 10 dB isolation up to 24.6 GHz.

ULTRA WIDEBAND ( 5GHz Band ) ATTENUATOR
KATC-0814 (PDF 82KB)(800MHz-5800MHz)

POWERFIL is completely different from the past, and is the method of isolating the power of IC one by one. That is, the filter is inserted + side and - side, and although DC is passed, Harmonics is completed isolated, and moreover, it is capable of passing 3,000mA current.

Coil element type Filter part that has the unique core material inserted with no lead , with volume line type and furthermore both sides are solder mounted and coils that are gilded.
POWERFIL EMI/EMC Countermeasure of D.C. Power Line Harmonics MAY/07/1999
POWERFIL(KHLC series) is the newest concept filter for power line. It fundamentally solves the EMI/EMC problem in the D.C. power supply line. And also filters out and clean the harmonics within the circuit. It is applicable also for the entire high-speed digital circuits.
