Sirenza Microdevices SNA-600 is a high-performance GaAs
Heterojunction Bipolar Transistor (MMIC) in die form. 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 65mA.
This MMIC requires only a single supply voltage. The use of an
external resistor allows for bias flexibility and stability. Its small
size (0.4mm x 0.4mm) and gold metallization make it an ideal
choice for use in hybrid circuits.
The SNA-600 is available in gel paks at 100 devices per con-
tainer. Also available in packaged form (SNA-676 & SNA-686).
