V2 Functional Schematic Description M/A-COM’s MA4P7455-1225 is a wideband, lower insertion loss, high IP3, Quad PIN Diode π Attenuator in a low-cost, lead free surface mount SOT-25 package. Four PIN Diodes in one package reduce design parasitics and improve circuit density. These PIN Diode Attenuators perform well where RF Signal Amplitude Control is required in 50 Ω Handset Circuits and 75 Ω 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.
