NBB-302
CASCADABLE BROADBAND
GaAs MMIC AMPLIFIER DC TO 12GHz
The NBB-302 cascadable broadband InGaP/GaAs MMIC amplifier is a low-cost,
high-performance solution for general purpose RF and microwave amplification
needs. This 50 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-302 provides flexibility and stability. The NBB-302 is
packaged in a low-cost, surface-mount ceramic package, providing ease of assem-
bly for high-volume tape-and-reel requirements. It is available in either packaged or
chip (NBB-300-D) form, where its gold metallization is ideal for hybrid circuit
designs.
