Richardson RFPD Introduces New High-Power SMT Attenuators from ATC

AT0603 Series covers DC–20 GHz

Richardson RFPD, Inc. announced today the availability and full design support capabilities for a new series of high-power SMT attenuators from American Technical Ceramics Corp. (ATC).

The AT0603 Series provides virtually flat loss over a broad frequency spectrum and is ideal where low noise, low inductance and low parasitic capacitance is required. The film metallization provides stable characteristics over temperature and time, and balanced Pi design provides even current distribution and accurate attenuation characteristics from DC to 20 GHz. The attenuators are ideal for impedance matching, input padding and signal-level tuning.

The AT0603 Series is designed to meet a wide range of RF and microwave large- and small-signal applications, including telecommunications, satellite communications, cellular base stations, microwave radio, ISM, RF and microwave power, military and aerospace, and test and measurement.

Additional key features of the AT0603 Series include:

• Nominal impedance: 50 ohms
• Values available: 3 dB, 6 dB, 10 dB
• Input power CW:
  • 1 W: 3 dB, 6 dB
  • 0.75 W: 10 dB
• VSWR: 1.25:1 typical
• Attenuation accuracy:
  • 1–9 dB: +/-0.50
  • 10 dB: +/-0.75
• Substrate material: AIN
• Resistors: Tantalum nitride
• Terminal: Thin film metal stack, Ni/Au
