TX noise leakage at RX band

Dear all,

I am reading this article about WCDMA TX noise calculation at RX band and I am struggling a bit on RFIC noise calculation (page 5). My understanding based on the following:

RFIC:
Noise in RX=-165dBc/Hz, I have converted it to dBm/Hz as RFIC output power is 0.5dBm, thus -165dBc/Hz+0.5dBm=-164.5dBm/Hz

Now based on page 5 equation I get

Noise generated by RFIC at RX band=Pn_rfic+PAgain+10log(BW)-ISOtx-rx [Note: BW=3.8MHz, ISOtx-rx=44dB]
=-115.7dBm

Above value is 4.45dB higher- I am not clear where did I do wrong calculation (if any).

It would be appreciated if you could provide me your kind comments.

Thanks in advance

No reply at all!

In the document you posted I think there is a mistake in the equation calculating Ptx_noise = -114.86 dBm.
I don't know what values were used in the equation to arrive to that number.
