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.

Function
Pin No.
Function
These PIN Diode Attenuators perform well where RF
Signal Amplitude Control is required in 50 Ω Hand-
set 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.
