Product Description
Stanford Microdevices’ SNA-500 is a GaAs monolithic
broadband amplifier in die form. This amplifier provides
19dB of gain when biased at 70mA and 5.0V. P1dB and
TOIP may be improved by 2dB by baising @ 100mA.
External DC decoupling capacitors determine low fre-
quency response. 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 packaged form (SNA-576, -586 & -587), its
small size (0.4mm x 0.4mm) and gold metallization make it an
ideal choice for use in hybrid circuits.
The SNA-500 is available in gel paks at 100 devices per
container.
