SNA-486

Product Description SNA-486 DC-6.5 GHz, Cascadable GaAs MMIC Amplifier Not Recommended for New Designs See Application Note AN-017 for Alternates Sirenza Microdevices’ SNA-486 is a GaAs HBT MMIC Amplifier housed in a low-cost, surface-mountable plastic package. The heterojunction increases breakdown voltage and minimizes leakage current between junctions. Cancellation of emitter junction non-linearities results in higher suppression of intermodulation products. 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-400), its small size (0.38mm x 0.38mm) and gold metallization make it an ideal choice for use in hybrid circuits.
