Product Description
SNA-476
Stanford Microdevices’ SNA-476 is a GaAs monolithic
broadband amplifier (MMIC) housed in a low-cost surface
mountable stripline ceramic package. This amplifier
provides 13dB of gain when biased at 70mA and 5.0V.
DC-8 GHz, Cascadable
GaAs MMIC Amplifier
External DC decoupling capacitors determine low
frequency 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 chip form (SNA-400), its small size (0.4mm x 0.4mm) and
gold metallization, make it an ideal choice for use in hybrid
circuits.
