Features
4 PIN diodes in a SOT-25 Plastic Package
Externally Selectable Bias and RF Matching
Network
Lead-Free (RoHS Compliant) Equivalents
Available with 260 °C Reflow Compatibility
5 – 3,000 MHz Useable Frequency Band
+ 45 dBm IIP3 @ 1 GHz (50 Ω)
2.8 dB Loss @ 1 GHz (50 Ω)
36 dB Attenuation @ 1 GHz (50 Ω)
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 Ω circuit applications.
Wideband Attenuation Range, Frequency Flatness,
and Input IP3 make these devices suitable for better
power level control in RF Amplifiers.
