Notes:
50. Differential output TXOUTP and TXOUTN.
51. Output via 4:1 balun (See section 4.3.1) and matching to 50Ω.
52. TxIF of 45MHz or 90MHz; ACPR measured as TIA-102.CAAB-B section 3.2.8.1.
53. Tested with 1910MHz LO and 45MHz IF, 2Vp-p differential input signal on I and Q; level at
955MHz measured relative to wanted signal at 1GHz.
