Product Description
Stanford Microdevices’ SLN-186 is a high performance
gallium arsenide heterojunction bipolar transistor MMIC
housed in a low-cost surface mount plastic package. A
Darlington configuration is used for broadband performance
from DC-4.0 GHz.
The SLN-186 needs only 2 DC-blocking capacitors and a
bias resistor for operation. Noise figure may be optimized by
using 2-element matching at the input to yield <2.0dB noise
figure.
This 50 Ohm LNA requires only a single supply voltage and
draws only 8mA. For broadband applications, it may be
biased at 6mA with minimal effect on noise figure and gain.
The SLN-186 is available in tape and reel at 1000, 3000 and
5000 devices per reel.
