Powerfilm™ Chip Attenuators
Up to 250 Watts, Up to 18 GHz
Powerfilm™ chip attenuators from API Inmet come in two varieties: “Temperature Stable” (standard) and “Temperature Variable” attenuators. The standard attenuators reduce the RF power uniformly at all temperatures while the temperature-variable chips are designed to reduce their attenuation at elevated temperatures to provide optimal response needed in signal- leveling applications. Chip attenuators are used in amplifier circuits, receivers, up/down converters, phase-matched arrays, and switching applications. Depending on desired specifications, chips are fabricated on BeO, Aluminum Nitride, or Alumina ceramics with either thin or thick resistors.
