AD831 is a low distortion, wide dynamic range, RF-IF in HF and VHF receivers It is a single-chip mixer suitable for down conversion, second mixer in DMR base stations, DC-baseband conversion, quadrature modulation and demodulation as well as Doppler shift detection.
The AD831 provides improved performance over passive mixers by providing a +24 dBm third-order crossover for -10 dBm LO power consumption without the need for a high-power LO driver and without the corresponding shielding and isolation issues.
The output amplifier of the mixer and the best source impedance, the SSB noise value of the mixer is 10.3 dB at 70 MHz. Unlike passive mixers, the AD831 has no insertion loss, eliminates the need for an external duplexer, and requires no passive termination.
