MADP-007167-12250T

RF Diode Overview

The MADP-007167-12250T is a wideband, moderate insertion loss, high IP3 PIN Diode π Quad Attenuator manufactured by MACOM Technology Solutions. It integrates four PIN diodes into a single low-cost surface mount SOT-25 package to reduce circuit parasitics and improve density. The device operates within a frequency band of 5 to 3,000 MHz. Key electrical specifications include a +45 dBm Input Intercept Point (IIP3) at 1 GHz in a 50 Ω system, an insertion loss of 2.8 dB at 1 GHz, and an attenuation value of 36 dB at 1 GHz. It is designed for variable RF amplitude control in 50 and 75 Ω applications.

• Power level control in RF amplifiers
• Wideband attenuation requiring high input intercept point

RF Diode Procurement Notes

Verify the specific ordering suffix to ensure compliance with RoHS standards and lead-free requirements. Confirm that the SOT-25 package type matches the target PCB footprint. Check for reflow compatibility ratings if high-temperature assembly processes are utilized. Ensure the selected variant aligns with the required 50 or 75 Ω impedance environment.

RF Diode Selection Notes

Select this component when a wideband attenuator covering 5 to 3,000 MHz is required alongside high linearity performance. The integrated quad-diode design offers a space-saving alternative to discrete implementations. Consider the 2.8 dB insertion loss and 36 dB attenuation capabilities at 1 GHz when designing for signal integrity and dynamic range requirements.

RF Diode Part Context

This part belongs to the MA4P series of PIN diode attenuators from MACOM. It serves as a functional equivalent to the MA4P290-1225T, offering similar quad-attenuator capabilities in the same SOT-25 package. The series is characterized by its use in broadband RF systems where compact size and high IP3 are critical design parameters.

RF Diode Replacement Considerations

The MA4P290-1225T is documented as a RoHS equivalent product with identical functional characteristics. Verify pinout compatibility and thermal performance before substitution. Other quad PIN diode attenuators in the SOT-25 package may require schematic adjustments due to differing biasing or matching network requirements.
