Targeted Electrical Specifi cations
T
Table 1. Performance at Vdd = Vsd = 2.7 V, Idd = 8 mA (R1 = 8.2 kOhm) nominal operating conditions
Notes:
1. Targeted performance at 1.575 GHz and 1.6017 GHz
2. Circuit losses not deembedded from demoboard. With losses deembedded, NF typical @1.575GHz = 0.82dB, @1.6017GHz = 0.83dB
3. 1.575 GHz IIP3 test condition: F
4. OOB Input IP2 test condition: Input jammer tones: 824.6MHz at -17dBm and 2400 MHz at -40dBm. Output IM2 tone at 1575.4 MHz
