Радиочастотный преобразователь AD831 стандартная полоса пропускания 0 1-500 МГц

AD831 500 МГц полоса пропускания Высокая линейность низкое искажение активный РЧ модуль смесителя

The AD831 is a low distortion, wide dynamic range, single chip mixer, suitable for HF and VHF Receiver RF-IF frequency, second mixer in DMR base station, DC-baseband conversion, quadrature modulation and demodulation, and ultrasound imaging, frequency shift detection and other applications.

 

Features:

• The AD831 has provide +24 dBm third-order intermodulation intercept point, realization of -10 dBm LO power, without the need for a high power LO drive.
• There is no corresponding shielding and isolation problems, therefore, compared with the passive mixer to improve the performance of the system, reduce the system cost.
• The mixer is designed as a single power supply, RF, IF and LO port with DC isolation capacitor, easy to use.
• The operating frequency of the RF and LO inputs can be as high as 500MHz.
• IF output is single ended voltage output.
• With 250 MHz output bandwidth.
• A single resistor connected between pins OUT and FB is used to set the gain.
• The amplifier has low DC offset characteristics, so it can be used in DC-baseband frequency conversion and quadrature amplitude demodulation.
• When the mixer's output amplifier and the optimum source impedance, the SSB noise figure of the mixer is 10.3dB at 70MHz.
• Different from the passive mixer, there is no insertion loss, no need external duplex device, and no need passive termination for AD831.
