Description and Applications
M/A-COM's MA4P274-1225T/MA4P7455-1225T is a
wideband, lower insertion loss, high IP3, Quad PIN
Diode
π
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
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.
