SNA-476-TR2

Product Description Stanford Microdevices’ SNA-476 is a GaAs monolithic broadband amplifier (MMIC) housed in a low-cost surface mountable stripline ceramic package. This amplifier provides 13dB of gain when biased at 70mA 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. Also available in chip form (SNA-400), its small size (0.4mm x 0.4mm) and gold metallization, make it an ideal choice for use in hybrid circuits. The SNA-476 is available in tape and reel at 1000, 3000 and 5000 devices per reel.
