Product Description
Sirenza Microdevices SNA-400 is a GaAs monolithic broad-
band amplifier (MMIC) in die form. This amplifier provides 13dB
of gain when biased at 65mA and 5.0V.
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-400 is available in gel pak at 100 devices per con-
tainer. Also available in packaged form (SNA-476 and SNA-
486).
