SNA-300 Datasheet, PDF (1/3 Pages) Stanford Microdevices – DC-3 GHz, Cascadable GaAs MMIC Amplifier

Product Description
Sirenza Microdevices’ SNA-300 is a GaAs monolithic broad-
band amplifier (MMIC) in die form. At 1950 MHz, this amplifier
provides 22dB of gain when biased at 35mA .
These unconditionally stable amplifiers are designed for use
as general purpose 50 ohm gain blocks. Its small size
(0.350mm x 0.345mm) and gold metallization make it an ideal
choice for use in hybrid circuits. The SNA-300 is 100% DC
tested and sample tested for RF performance.
External DC decoupling capacitors determine low frequency
response. The use of an external resistor allows for bias
flexibility and stability.
The SNA-300 is supplied in gel paks at 100 devices per pak.
Also available in packaged form (SNA-376 & SNA-386)
