Functional Schematic
Description
M/A-COM’s MA4P274-1225 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 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.
