AD8362 50HZ-3.8GHZ,RF Radio frequency Detector / power /RMS detector amplifiers

Description

Feature :
1. Working frequency band: Operating frequency can be 50Hz to 3.8GHz, suitable for wideband power detector, having a flat input and output response.
2. High dynamic range: the input dynamic range of 60dB, in a 50Ω system, the input signal from -52 dBm to + 8dBm.
3. Precision, high linearity to provide an accurate decibels (dB) as the unit of linear output voltage, 50mV / dB.
4. True RMS power detector AD8362 is a true rms responding power detector, which has nothing to do with the signal waveform measurements, can detect RF power complex modulation signals (including CDMA, W-CDMA, 8PSK, QAM and OFDM signals) suitable for IS95, CDMA2000, 3GPP, GSM / EDGE, MMDS and other broadband access devices.
5. There are two modes of operation
AD8362 has a power measurement and control modes. Figure 1, in the power measurement mode, VOUT and VSET
Proportional to the logarithm pin is directly connected to the output voltage and input RMS power, the input signal for each additional 1dB, the output voltage Vout increases 50 mV, can reach (Vs-0.1) V, the voltage readings directly reflect the size of the power This mode of operation is suitable for power meter or doing power detection purposes in the device. Another mode of operation is the controller mode, shown in Figure 2, at the end VSET set a voltage reference value, when the AD8362 detects the power voltage is greater than the reference voltage value, the voltage Vout outputs a high level when the AD8362 is detected power voltage value is less than the reference voltage value, the voltage Vout measured power utilization AD8307, typical linear slope of 0.025 V / dB, the measurement range of -75 dBm ~ + 16 dBm. . Shielding shell and anti-reverse protection diode
Third, technical indicators
1, power supply voltage: 5V DC (typical current 20mA)
2, the input signal dynamic range: -52 dBm to + 8dBm
3, module slope and support change detection and control of two power measurements.
4, Bandwidth: 50Hz to 3.8GHz
5, shielded with a metal shell
6 to provide a PDF schematic
7, the input impedance: 50 ohms (the input signal to match with Valencia)
