Description and Applications

M/A-COM's MA4P274-1225T/MA4P7455-1225T is a

wideband, lower insertion loss, high IP3, Quad PIN

Diode p Attenuator in a low-cost, surface mount

SOT-25 package. Four PIN Diodes in one package

reduce design parasitics and improve circuit density.

Series

Bias

These PIN Diode Attenuators perform well where RF

Signal Amplitude Control is required in 50 W

Handset Circuits and 75 W 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.
