5. All components are 0603 in size unless otherwise noted.
6. 1% tolerance is for R1 and R2.
7. The dc resistance of L1 and L2 should be less than 1 ohm.
1. Balun, board, and connector losses have not been extracted, but typically account for
0.4 dB loss midband and 1.1 dB loss at 860 MHz.
2. CSO, CTB, & XMOD are measured at +34 dBmV/channel, 79 channels Flat Loading.
3. OIP2 is measured at f1 + f2 at 5 dBm / tone.
4. OIP3 is measured at +5 dBm / tone with 1 MHz spacing.
