Description The ad831 has is a low distortion wide dynamic range single chip mixer suitable for such as HF and VHF Receiver RF IF frequency DMR base station in the second mixer a DC baseband conversion quadrature modulation and demodulation and ultrasound imaging Doppler frequency shift detection and other applications Characteristics 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 ports with DC isolation capacitor easy to use The operating frequency of the RF and LO inputs can be as high as 500MHz IF output for 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 mixers output amplifier and the optimum source impedance the SSB noise figure of the mixer is 10 3 dB at 70 MHz Different from the passive mixer there is no insertion loss no external duplex device and no passive AD831 Technical indicators RF input 0 1 500MHzRF input 10dBm 1dB compression point Local oscillator input 0 1 500MHz
