SNA-486 Datasheet, PDF (1/5 Pages) List of Unclassifed Manufacturers – DC - 6.5 GHZ CASCADABLE GAAS MMIC AMPLIFIER

Product Description
Sirenza Microdevices’ SNA-486 is a GaAs HBT MMIC Amplifier
housed in a low-cost, surface-mountable plastic package.
The heterojunction increases breakdown voltage and
minimizes leakage current between junctions. Cancellation
of emitter junction non-linearities results in higher suppression
of intermodulation products.
SNA-486
DC-6.5 GHz, Cascadable
GaAs MMIC Amplifier
Not Recommended for New Designs
See Application Note AN-017 for Alternates
The use of an external resistor allows for bias flexibility and
stability. These unconditionally stable amplifiers are designed
for use as general purpose 50 ohm gain blocks.
Also available in chip form (SNA-400), its small size (0.38mm
x 0.38mm) and gold metallization make it an ideal choice for
use in hybrid circuits.
