Product Description
Sirenza Microdevices SNA-686 is a high performance Gallium
Arsenide Heterojunction Bipolar Transistor MMIC Amplifier. A
Darlington configuration is utilized for broadband performance up
to 6 GHz. The heterojunction increases breakdown voltage and
minimizes leakage current between junctions. Cancellation of
emitter junction non-linearities results in higher suppression of
intermodulation products. Typical IP3 at 850 MHz with 65mA is
34 dBm.

GaAs HBT MMIC Amplifier
NGA-686 Recommended for New Designs
These unconditionally stable amplifiers provide 11 dB of gain and
17.7 dBm of 1dB compressed power and require only a single
positive voltage supply. Only 2 DC-blocking capacitors, a bias
resistor and an optional inductor are needed for operation.
