General Information

average of complex modulation formats across a wide dynamic range, irrespective of signal bandwidth. The dual range Modified Barrier Integrated Diode (MBID)1 package includes further refinements to improve power handling allowing accurate measurement of high level signals with high crest factors without incurring damage2 to the sensor.

These sensors measure average RF power on a wide variety of modulated signals and are independent of the modulation bandwidth. They are ideally suited to the average power measurement of multi-tone and spread spectrum signals such as CDMA, W-CDMA and digital television formats. Also, pulsed, TDMA signals can be measured within the constraints detailed in “Measuring TDMA Signals” on page 25.

The results are displayed on a compatible3 power meter in logarithmic (dBm or dB) or linear (Watts or %) measurement units.
