Powerfilm™ chip attenuators from Spectrum Control Inmet come in two varieties: “Temperature Stable” (standard) and “Temperature Variable” RF attenuators.
The standard RF 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. y
Chip attenuators are used in amplifier circuits, receivers, up/down converters, phase-matched arrays, and switching applications. Depending on desired specifications, chip RF attenuators are fabricated on BeO, Aluminum Nitride, or Alumina ceramics with either thin film or thick film resistors. Other RF attenuator designs, values and options may be available upon request.
Temperature Variable Chip Attenuators
Up to 18GHz
Powerfilm temperature-variable chip attenuators are designed to reduce their attenuation at elevated temperatures to provide optimal response needed in signal-leveling applications. TCA chips are fabricated on Alumina ceramics with proprietary thick resistors. Other RF attenuator designs, values and options may be available upon request.
