ADL5903 is a solution for a variety of high frequency systems requiring accurate measurement of signal power independent of waveform characteristics. The ADL5506 RF detector is a complete subsystem for the measurement of RF signals in a wide range of wireless terminal devices. Both detectors come in small packages with low-power operation.
Features of the ADL5903 include;
- Single-ended input dynamic range of 35 dB, 50Ω source-compatible
- Accurate RMS-to-DC conversion from 200 MHz to 6 GHz
- Linear in decibels output, scaled 35.5 mV/dB at 900 MHz
- Waveform and modulation independent
Features of the ADL5506 include;
- Typical dynamic range: 45 dBm to 0 dBm
- Frequency range from 30 MHz to 4.5 GHz
- Stable linear-in decibel response
- Low power: 3.8 mA at 3V (with < 1 µA in Disable Mode)
