Product Description
Stanford Microdevices’ SNA-276 is a GaAs monolithic
broadband amplifier (MMIC) housed in a low-cost surface
mountable stripline package. This amplifier provides 16dB of
gain when biased at 50mA and 4V.
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-200), its small size (0.33mm x 0.33mm) and
gold metallization, make it an ideal choice for use in hybrid
circuits.
The SNA-276 is available in tape and reel at 1000, 3000 and
5000 devices per reel.
