SNA-300 Datasheet, PDF (1/3 Pages) Stanford Microdevices – DC-3 GHz, Cascadable GaAs MMIC Amplifier

Product Description
Stanford Microdevices’ SNA-300 is a GaAs monolithic broad-
band amplifier (MMIC) in die form. This amplifier provides
22dB of gain when biased at 35mA and 4V.
External DC decoupling capacitors determine low frequency
response. The use of an external resistor allows for bias
flexibility and stability.

DC-3 GHz, Cascadable
GaAs MMIC Amplifier
These unconditionally stable amplifiers are designed for use
as general purpose 50 ohm gain blocks. Also available in
packaged form (SNA-376, -386 & -387), its small size (0.33mm
x 0.33mm) and gold metallization make it an ideal choice for
use in hybrid circuits.
The SNA-300 is available in gel paks at 100 devices per
container.
