TRF3705: TRF3705 Input/Output Level

Part Number: TRF3705
Other Parts Discussed in Thread: DAC3482


I'm Alber as a FAE in Arrow Korea.

My customer use DAC3482 & TRF3705.

My customer has a question about TRF3705 Input/Output Level as aspect of RF Level.

IQ Modulator has 4 input port(I+, I-, Q+, Q-).

If the modulator is ideal(No gain and No conversion loss)and the output power of modulator(Single-Ended) is 0dBm, is this right that each input power(I+, I-, Q+, Q-) is -6dBm or 0dBm?

My customer are confusing about this.

They said, I & Q signal is same and different only phase.

Please answer clearly.
