| Product Description Sirenza Microdevices' SNA-200 is a GaAs monolithic broadband amplifier (MMIC) in die form. At 1950 MHz, this amplifier provides 16dB of gain when biased at 50mA. These unconditionally stable amplifiers are designed for use as general purpose 50 ohm gain blocks. Its small size (0.33mm x 0.33mm) and gold metallization make it an ideal choice for use in hybrid circuits. External DC decoupling capacitors determine low frequency response. The use of an external resistor allows for bias flexibility and stability. The SNA-200 is supplied in gel paks at 100 devices per pak. Also available in packaged form (SNA-276 & SNA-286) Output Power vs. Frequency 16 15 SNA-200 DC-6.5 GHz, Cascadable GaAs MMIC Amplifier Not Recommended for New Designs, Use SNA-200S Product Features * Cascadable 50 Ohm Gain Block * 16dB Gain, +14dBm P1dB * 1.5:1 Input and Output VSWR * Operates From Single Supply * Chip Back Is Ground dBm 14 13 12 0.5 1 1.5 2 4 6 8 10 GHz Symbol GP GF BW3dB P1dB NF VSWR Parameter Small Signal Pow er Gain Gain Flatness 3dB Bandw idth Output Pow er at 1dB Compression Noise Figure Input / Output Units dB dB dB dB GHz dBm dB Frequency 850 MHz 1950 MHz 2400 MHz 0.1-4.0 GHz Min.
