Description and Applications
M/A-COM's MA4P274-1225T/MA4P7455-1225T is a wideband, lower insertion loss, high IP3, Quad PIN Diode Attenuator in a low-cost, surface mount SOT-25 package. Four PIN Diodes in one package reduce design parasitics and improve circuit density. These devices are offered with standard Sn/Pb plating, as well as with 100% matte Sn plating on our RoHS compliant equivalent device. These PIN Diode Attenuators perform well where RF Signal Amplitude Control is required in 50 Handset Circuits and 75 Broadband CATV Systems. Exceptional Insertion Loss, Attenuation Range, and IP3 at <10 mA bias make these devices suitable for better power level control in RF Amplifiers.
