Description and Applications
M/A-COM's
MA4P290-1225T
&
MADP-007167-
12250T RoHs equivalent product is a wideband,
moderate insertion loss, high IP3, PIN Diode
π
Quad Attenuator in a low-cost, surface mount SOT-
25 package. Four PIN Diodes in one package re-
duce circuit parasitics and improve circuit density.
These PIN Diode Attenuators perform well where
Variable RF Amplitude Control is required in 50 and
75
circuit applications.
