Product Description
Stanford Microdevices’ SNA-676 is a high-performance
GaAs Heterojunction Bipolar Transistor (MMIC) housed in a
low-cost surface mountable stripline package. A Darlington
configuration is utilized for broadband performance to 6.5
GHz.
These unconditionally stable amplifiers provide 11dB of gain
and +18dBm of P1dB when biased at 5.7V and 70mA. This
MMIC requires only a single suply voltage. The use of an
external resistor allows for bias flexibility and stability.
Also available in chip form (SNA-600), its small size (0.4mm
x 0.4mm) and gold metallization make it an ideal choice for
use in hybrid circuits.
The SNA-676 is available in tape and reel at 1000, 3000 and
5000 devices per reel.
