Quad PIN Diode π Attenuator
5 –3000 MHz
Features
• 4 PIN Diodes in SOT-25 Plastic Package
• Externally Selectable Bias and RF Match
Network
• 5 – 3,000 MHz Useable Frequency Band
• + 43 dBm IP3@ 1 GHz (50 Ω)
• 1.0 dB Loss @ 1 GHz (50 Ω)
• 30 dB Attenuation @ 1 GHz (50 Ω)
• Lead-Free (RoHS Compliant) equivalent
available with 260 °C reflow compatibility
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.
