Susumu PAT3042S high precision chip attenuator

Susumu PAT3042S Series

  • High precision chip attenuator
  • Surface mount design with an 1612 chip size
  • Attenuation of 0dB to 10dB (1dB steps), 16dB or 20dB
  • Attenuation tolerance down to ±0.3dB
  • Impedance of 50Ω or 75Ω
  • Temperature range from −55°C to +125°C
  • Compliant

The PAT3042S high precision chip attenuator is part of the PAT series of thin film attenuators designed for high precision applications from Susumu. The PAT3042S model has a 1612 chip size and is available in an attenuation range of 0dB to 10dB in 1dB steps, 16dB and 20dB. This series utilises a similar wrap-around terminal to that of regular chip resistors making them easy to mount. One chip attenuator covers a wide frequency range of 3GHz (50Ω impedance) or 2GHz (75Ω impedance). These attenuators have been developed to withstand operating temperatures between −55°C to +125°C.

  • High precision chip attenuator
  • Surface mount design with an 1612 chip size
  • Attenuation of 0dB to 10dB (1dB steps), 16dB or 20dB
  • Attenuation tolerances of ±0.3dB or ±0.5dB
  • Impedance of 50Ω (C) or 75Ω(D)
  • VSWR of <1.2 (50Ω) or <1.3 (75Ω)
  • Operating frequencies of DC∼3GHz (50Ω) or DC∼2GHz (75Ω)
  • Rated power of 250mW
  • Temperature range from −55°C to +125°C
  • Rated operating temperature +70°C

The Susumu PAT3042S high precision chip attenuator is ideal for the following applications:

  • Cell phone base stations
  • Wireless communication modules
  • Wide band measurement instrumentation
