SNA-400

Product Description Sirenza Microdevices’ SNA-400 is a GaAs monolithic broadband amplifier (MMIC) in die form. This amplifier provides 13dB of gain when biased at 65mA and 5.0V. External DC decoupling capacitors determine low frequency response. 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. Its small size (0.4mm x 0.4mm) and gold metallization make it an ideal choice for use in hybrid circuits. The SNA-400 is available in gel pak at 100 devices per container. Also available in packaged form (SNA-476 and SNA486).
