| 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.
