Quadrature demodulator in UHF band with LO input

The RF system operates in UHF band (50MHz-850MHz). I have designed a transmitter using quadrature modulator AD8345 and it works well.
Now I want to design a quadrature demodulator. The AD8348 is a natural choose. However, AD8348 needs 2xLO input. For instance, if the frequency of the input RF signal is 700MHz, we must give a 1400MHz LO signal for the AD8348.
So, please recommend a quadrature demodulator with 1xLO input for me?
