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 damage
2
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 compatible
3
power meter in logarithmic (dBm
or dB) or linear (Watts or %) measurement units.
