NLB-300
CASCADABLE BROADBAND
GaAs MMIC AMPLIFIER DC TO 10GHz
0
Typical Applications
• Narrow and Broadband Commercial and
Military Radio Designs
• Gain Stage or Driver Amplifiers for
MWRadio/Optical Designs (PTP/PMP/
LMDS/UNII/VSAT/WLAN/Cellular/DWDM)
• Linear and Saturated Amplifiers
Product Description
The NLB-300 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 NLB-300 provides flexibility and stability. The
NLB-300 is packaged in a low-cost, surface-mount plastic
package, providing ease of assembly for high-volume
tape-and-reel requirements.
