1. Description
AD8314ARMZ is a complete low-cost subsystem, suitable for Measurement and control of radio frequency signals in the frequency range 100 MHz to 2.7 GHz, with a typical dynamic range of 45 dB, Designed to be used in various cellular phones and other Wireless equipment. It provides a wider dynamic range and better The accuracy may be higher than using a discrete diode detector. exist In particular, its temperature stability is very good -40°C to +85°C operating range. Its high sensitivity allows control at low power levels, so Reduce the need to couple to detector. It is essentially a voltage responsive device with Typical signal range is 1.25 mV to 224 mV rms or –58 dBV to −13 dBV. This is equivalent to −45 dBm to 0 dBm, again 50 Ω. For convenience, the signal is internally AC coupled, using a A 5 pF capacitor is connected in parallel with a 3 kΩ load and has 2 pF. This high-pass coupling has a corner at about 16 MHz, Determine the minimum operating frequency. Therefore, the The source can be DC grounded. AD8314 provides two voltage outputs. The first one, V_UP, As the input signal increases from close to ground to approximately 1.2 V The level increased from 1.25 mV to 224 mV. This output is designed to Used in measurement mode. Capacitors can be connected When it needs to be between the V_UP and FLTR pins Increase the average input time interval The waveform occurs. The second output V_DN is the inverse of V_UP, but has Two times the slope and offset by a fixed amount. This output starts Approximately 2.25 V (assuming power supply voltage ≥ 3.3 V) Minimum input and drop to a value close to the ground Maximum input. This output is used for analog control Cycle application. A set point voltage is applied to VSET, and Then use V_DN to control VGA or power amplifier. here Again, an external filter capacitor can be added to extend Average time. AD8314 is available in 8-lead MSOP and 8-lead LFCSP packages It is packaged and consumes 4.5 mA from a 2.7 V to 5.5 V power supply. When power is off, the typical sleep current is 20 µA.
