Description

AD8362 True RMS Response Power Detector 50MHz-3.8GHz Fully Shielded Shell
Description
1. Product application:
1. Working frequency bandwidth: The working frequency can be from 50Hz to 3.8GHz, suitable for wide-band power detection, with flat input and output response.
2. High dynamic range: The input dynamic range is up to 60dB. In a 50Ω system, the input signal can range from -52 dBm to +8dBm.
3. High accuracy and linearity Provide an accurate linear output voltage in decibels (dB), 50mV/dB.
4. True RMS power detection AD8362 is a true RMS response power detector. Its measurement results are independent of signal waveforms and can detect the RF power of complex modulation signals (including CDMA, W-CDMA, 8PSK, QAM and OFDM signals). Suitable for IS95, CDMA2000, 3GPP, GSM/EDGE, MMDS and other broadband access equipment.
5. There are two working modes
AD8362 has two working modes: power measurement and controller. In Figure 1, in the power measurement mode, VOUT and VSET
The pin is directly connected, and the output voltage is proportional to the logarithm of the rms value of the input power. When the input signal increases by 1dB, the output voltage Vout increases by 50 mV, up to (Vs-0.1)V. The voltage reading directly reflects the power , This working mode is suitable for power meter or power detection in equipment. Another working mode is the controller mode. As shown in Figure 2, a reference voltage value is set at the VSET terminal. When the power voltage value detected by AD8362 is greater than the reference voltage value, the voltage Vout outputs a high level. When AD8362 detects When the power voltage value of is less than the reference voltage value, when the voltage Vout uses AD8307 to measure the power, the typical linear slope is 0.025 V/dB, and the measurement range is -75 dBm~+16 dBm. . With shielding shell and anti-reverse connection protection diode.
