IMA Series Surface Mount
Thick Film Attenuator
IMA Series Custom family surface mount thick film attenuators are
compact, high performance devices especially suited to RF and
microwave applications. Performance is based on the attenuator
operating in a matched continuous 50 ohm system, with proper
device mounting and workmanship.
