1. Balun, board, and connector losses have not been extracted, but typically account of
0.4 dB loss midband and 1.1 dB loss at 860 MHz.
2. CSO, CTB, & XMOD are measured at +39 dBmV/channel, 77 channels Flat Loading.
3. OIP2 is measured at f1 + f2 at 8 dBm / tone.
4. OIP3 is measured at 8 dBm / tone with 10 MHz spacing.

The transformers, L1 and L2, used on the WJ evaluation board are handwound baluns using these materials: 6
turns bifilar wire (MWS B2383211) around a ferrite core (TDK, H5C2-T3.1-1.3-1.3). An SMT transformer
(M/A Com ETC1-1-13) can also be used.
