AD8333 single ended drive to RF input and other

Hi All,


For the AD8333, is it possible to single ended drive to RF input?

The data sheet mentioned that the LO input can drive single ended signal.

If possible, my customer wants to drive single ended RF signal to the RF input elimination single to differential amplifier.

When drive with single ended signal, what degradation would be anticipated?


The AD8333 has two channels of demodulator and phase shifter circuits.

When only one channel is needed, how to handle the unused terminals.

I expect the connection of 0.1uF capacitors between RF input terminal and GND will be needed. And also connection of around 100ohm resisters between I/Q output terminal and GND will be needed.

If any other treatment is needed, please advise us.


Best Regards,
