Chip Attenuators
Powerfilm™ Chip Attenuators - Precision Surface-Mount RF Attenuation Solutions
Spectrum Control’s chip attenuators are high-reliability, compact surface-mount devices designed for RF and microwave systems where precise attenuation, excellent impedance matching, and rugged performance are required. Whether used in wireless infrastructure, radar subsystems, phased arrays, up/down converters, or space/military electronics, these SMD attenuators deliver stable, repeatable performance in demanding environments.
-
Broad frequency coverage: any models cover from DC up to 12.4 GHz (or higher up to 18 GHz or beyond) for wideband applications
-
Precision attenuation values: standard dB increments (0 to 20 dB and beyond) with tight tolerances for accurate signal control
-
Compact SMD/chip package: suitable for high-density PCB layouts and automated assembly
-
Excellent VSWR (low reflection): maintains integrity of RF path with minimal return loss
-
High reliability and temperature stability: operating temperature range from -55°C to +150°C; attenuation stability specified as low as 0.0001 dB/dB/°C
-
Multiple substrates and finishes: available on alumina, aluminum nitride, BeO; options for tin-lead, lead-free, gold plating
-
Customizable: select non-standard dB values, tinning/finishes, special substrate or power rating if our standard catalog doesn’t meet your requirement
