TRF371135 Noise Figure and Gain Information for the MIXoutp/n and MIXQoutp/n output pins

Other Parts Discussed in Thread: TRF371135

I plan to use the direct mixer output pins of the TRF371135 demodulator (MIXoutp/n and MIXQoutp/n), so I would like to know both the Noise Nigure and the Gain from the input to these outputs, especially in the 5G band.

The gain of the mixers is approximately 9 dB at 3.5 GHz and the NF is approximately 10 dB. The gain and NF do shift with respect to frequency. You can utilize the gain slope shown in the datasheet and apply the same slope with the starting point at 3.5 GHz to get the approximate performance at any arbitrary frequency.
