- DC to 26.5 GHz, DC to 40 GHz frequency coverage
- Optional calibration data
- 0 to 11 dB, 70 dB, 90 dB
- 1 dB steps, 10 dB steps
- Excellent repeatability
- High accuracy
- Excellent reliability, long life
- Exceptionally low insertion loss These attenuators offer repeatability of better than 0.03 dB and excellent life (greater than 5 million switching cycles per section). This family of programmable step attenuators offers coaxial measure- ments to 26.5 GHz (K models) or to
40 GHz (L models), in a compact,
