MSAT-21, MSAT-22, MSAT-23 SERIES
The MSAT series Thin Film Power chip attenuators provide attenuation accuracy for frequencies through
MSAT
20 GHz. They offer the low noise, stray capacitance and tight tolerance of Thin Film in compact sizes that
250mW.
make them ideal for smaller microwave and stripline applications at operating powers to 250mW.
