RF Diode Procurement Notes

Verify the specific ordering suffix against official MACOM documentation to confirm the exact package style and packaging format. Ensure that the component meets all applicable environmental compliance standards required for the intended manufacturing process before finalizing procurement orders.

RF Diode Selection Notes

Select this component when a general-purpose silicon PIN diode with moderate speed and low capacitance is required. The Series Tee configuration simplifies biasing network layout compared to single diodes. Evaluate thermal derating coefficients if high RF incident power levels are expected in the application environment.

RF Diode Part Context

This part belongs to the MACOM SMPP series of surface mount plastic PIN diodes. It shares the same electrical characteristics as the MADP-007448-0287BT but utilizes the smaller SOT-323 (Case Style 1146) package instead of the SOT-23 (Case Style 287) footprint.
