Does the bias circuit that the EN pin controls, produce the DC common-mode voltage for the differential baseband inputs (QP, QN, IP, and IN)?
Apologies for the delayed response. You will need to apply the DC common-mode bias voltages. The EN pin controls the LO amplifier portion of the circuit.
I'm looking for a bias circuit for the I and Q inputs when using LF baseband signals. My intend is to use the chip for amateur radio SSB on 2400 MHz. I hope someone can help me.
