HFR-RFA53SDLF-1GZ00 Datasheet, PDF (1/4 Pages) IRC - a TT electronics Company. – High Frequency Surface Mount Attenuators

High Frequency
Surface Mount Attenuators
RFAXX Series
• Low return loss
• RoHS compliant
• High power chip attenuators
• Long life, temperature stable thin film on ceramic technology
The RFAXX series of 50Ω high frequency attenuators are available
in a variety of sizes and termination styles to suit applications for mounting
on heat sinks or normal PC board materials. High thermal conductivity aluminum nitride substrates provide the
low resistance thermal path for high power dissipation applications. Frequency performance up to 4GHz assures
proper operation in RF and microwave power amplifiers, RF transmitters and receivers and RF power sources.
