These compact devices from State of the Art (SOTA), Inc. are ideal for a wide range of applications including power switches, frequency converters, antennas, power dividers, low noise amplifiers, and passive signal buffers. They are offered in case sizes of 0706, 1005, and 1512 with several different termination styles including style "AC" top-sided metallization, style "CC" 3-side wrap-around, and style "EC" bottom metallized wrap-around. The devices are available with attenuation factors of 1 - 20 dB in 1/2 dB increments with a frequency range from DC - 20 GHz. Available tolerances are ۯ dB and ۫ dB. Temperature coefficient of attenuation is as low as ۪.0001 dB/dB/°C. Power dissipation ranges from 1/8 W to 1/2 W. VSWR is as low as 1.05. Attenuation stability is typically better than ۪.5 over the entire frequency range.
