TRF370417 - Output Noise Floor vs Frequency and LO Power

Other Parts Discussed in Thread: TRF370417, TRF3705

Hello,

My customer has a question about TRF370417.

[Q]

Do you have a data with respect to Output Noise Floor vs Frequency and LO Power ?

They are going to use TRF370417.

Their LO frequency is 6GHz.

They want to minimize the output noise floor.

Best Regards,

Hiroshi Katsunaga

  • Katsunaga-san:

    I do not explicitly have the data available for the TRF3704, but the performance characteristic is shown in the TRF3705 D/S.  The '04 will have similar behavior with respect to output noise improvement with LO power increase.  To improve output noise floor you can increase the LO drive power.  I expect a 1 to 2 dB improvement at 6 GHz when the LO drive level is increased to +4 to +6 dBm.
