Notes: 7. Measurements at 2GHz obtained using demo board described in Fig 5. 8. 2GHz OIP3 test condition: FRF1 = 2.0 GHz, FRF2 = 2.01 GHz with input power of -20dBm per tone measured at lower side band. 9. For NF data, board losses of 0.12dB at the input have been de-embedded. 10. Use proper bias, heatsink and derating to ensure maximum channel temperature is not exceeded. See absolute maximum ratings and applica- tion note for more details. Electrical Specifications [7], [10] TA = 25 °C, Vdd =5V @ 280mA, RF performance at 2.0 GHz, given for each of the 2 RF paths, measured on demo board (see Fig. 5) unless otherwise specified.
