SNA-500 Datasheet, PDF (1/3 Pages) Stanford Microdevices – DC-3 GHz, Cascadable GaAs MMIC Amplifier

Product Description
Sirenza Microdevices’ SNA-500 is a GaAs monolithic broad-
band amplifier in die form. This amplifier provides 19dB of gain
when biased at 65mA and 5.0V.
SNA-500
DC-3 GHz, Cascadable
GaAs MMIC Amplifier
External DC decoupling capacitors determine low frequency re-
sponse. 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. 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 con-
tainer. Also available in packaged form (SNA-576 and SNA-
586).
