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
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.
