Typical Applications
• Narrow and Broadband Commercial and
Military Radio Designs
• Linear and Saturated Amplifiers
Product Description
The NBB-312 cascadable broadband InGaP/GaAs MMIC
amplifier is a low-cost, high-performance solution for gen-
eral purpose RF and microwave amplification needs. This
50Ω 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 NBB-312 provides flexibility and stability. The
NBB-310 is packaged in a low-cost, surface-mount
ceramic package, providing ease of assembly for high-
volume tape-and-reel requirements. It is available in
either 1,000 or 3,000 piece-per-reel quantities. Connec-
torized evaluation board designs optimized for high fre-
quency are also available for characterization purposes.
