LM YN AD8302 Wideband Logarithmic Amplifier Wideband Linear Multiplier Phase Detector Module Low Frequency to 2.7G for OPA695
- ...ons. It requires few external components and a single supply of 2.7 V–5.5 V. The ac-coupled input signals can range from –60 dBm to 0 dBm in a 50 ohm system, from low frequencies up to 2.7 GHz. Both subsystems have an output bandwidth of 30 MHz, which may optionally be reduced by the addition of external filter capacitors. 003cbr003e.
- The AD8302 can be used in controller mode to force the gain and phase of a signal chain toward predetermined setpoints.003cbr003e.
- The AD8302 includes a phase detector of the multiplier type, but with precise phase balance driven by the fully limited signals appearing at the outputs of the two logarithmic amplifiers. Thus, the phase accuracy measurement is independent of signal level over a wide range. The signal inputs are single-ended, allowing them to be matched and connected directly to a directional coupler. Their input impedance is nominally 3 kΩ at low frequencies. 003cbr003e.
- The phase and gain output voltages are simultaneously available at loadable ground referenced outputs over the standard output range of 0 V to 1.8 V. The output drivers can source or sink up to 8 mA. A loadable, stable reference voltage of 1.8 V is available for precise repositioning of the output range by the user.003cbr003e.
