NBB-400

RF Amplifiers Overview

The Qorvo NBB-400 is a cascadable broadband InGaP/GaAs MMIC amplifier designed for general-purpose RF and microwave applications. It operates from DC to 8 GHz with a typical gain of 15.5 dB at 2 GHz. The device features a P1dB compression point of 15 dBm at 2 GHz, a noise figure of 4.3 dB, and an OIP3 of 26 dBm. It requires a supply voltage of 3.9 V and draws 47 mA of current. The component is housed in a Micro-X-4 surface-mount package and supports operation between -45°C and +85°C.

RF Amplifiers Feature Summary

RF Amplifiers Procurement Notes

Verify the specific suffix (e.g., D, T1) as it indicates packaging or lot variations rather than functional changes. Confirm lifecycle status, as some variants are marked obsolete. Ensure compatibility with existing PCB footprints for the Micro-X-4 package. Cross-reference datasheet revisions to confirm pinout consistency before integration.

RF Amplifiers Selection Notes

Select this component when a wide bandwidth up to 8 GHz is required without tuning. The cascadable design allows system designers to stack units for increased gain while maintaining linearity. Consider the 47 mA current draw for power budget calculations. Verify that the 15 dBm output power meets the dynamic range needs of the subsequent stage.

RF Amplifiers Part Context

The NBB-400 belongs to Qorvo's family of broadband MMIC amplifiers. It utilizes InGaP/GaAs technology to achieve low noise and high linearity across a wide spectrum. This series targets cost-sensitive applications requiring reliable RF performance in small packages suitable for modern wireless infrastructure.

RF Amplifiers Replacement Considerations

NBB-400-D and NBB-400-T1 are confirmed substitute part numbers representing different packaging options for the same core device.
