Notes
1. Measured and guaranteed only on UAA3522 evaluation board.
2. The IF output has open collectors which are supplied via external inductors. External resistors are also needed to
3. Value includes losses due to the printed circuit board and balun.
4. Value is guaranteed only for the P
5. For a given RF input power, the value is the difference in the power measured at the IF output when the LNA is
6. This value is guaranteed within the temperature range 10 to +70 C.
7. Voltage gain is defined as the differential baseband output voltage (either at pins IA/IB or pins QA/QB) divided by the
8. Value refers to differential voltage at pins RXIIFA and RXIIFB (1 k input impedance).
9. Value includes printed circuit board and balun losses.
10. R
11. Guaranteed at T
12. With specified LC tuned circuit (33 nH, 15 pF) connected as shown in Fig.4.
13. Defined for the typical input power.
14. Oscillator configured as shown in the evaluation board diagram Fig.7.
