NBB-400

DC - 8 GHz Cascadable Broadband GaAs MMIC Amplifier, Packaged

Qorvo's NBB400 cascadable broadband InGaP/GaAs MMIC amplifier is a low-cost high-performance solution for general purpose RF and microwave amplification needs. This 50 ohm gain block is based on a reliable HBT proprietary MMIC design providing unsurpassed performance for small-signal applications. Designed with an external bias resistor the NBB400 provides flexibility and stability. The NBB400 is packaged in a low-cost surface-mount ceramic package providing ease of assembly for high-volume tape-and-reel requirements.
