STANFORD SNA-576-TR3

Product Description
SNA-576
Stanford Microdevices’ SNA-576 is a GaAs monolithic
broadband amplifier housed in a low-cost stripline ceramic
package. This amplifier provides 19dB of gain when biased
at 70mA and 5.0V.
DC-3 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-500), its small size (0.4mm x
0.4mm) and gold metallization make it an ideal choice for
use in hybrid circuits.
The SNA-576 is available in tape and reel at 1000, 3000 and
5000 devices per reel.
