Product Description
Stanford Microdevices’ SLN-386 is a high performance GaAs
Heterojunction Bipolar Transistor (HBT) MMIC housed in a
low-cost 85 mil (2.2mm) diameter plastic package. This HBT
MMIC is fabricated using molecular beam epitaxial growth
technology which produces reliable and consistant
performance from wafer to wafer.
SLN-386
DC-2.5 GHz
50 Ohm LNA MMIC Amplifier
The SLN-386 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 <3.0 dB noise
figure.
This 50 Ohm LNA requires only a single supply voltage and
draws only 18mA which makes it an ideal choice for wireless
subscriber equipment including cellular, PCS, CDPD, wireless
data and pagers.
The SLN-386 is available in tape and reel at 1000, 3000 and
5000 devices per reel.
