Objective specification
Low power dual-band GSM transceiver
with an image rejecting front-end
UAA3522HL
Notes
1.
2.
Measured and guaranteed only on UAA3522 evaluation board.
The IF output has open collectors which are supplied via external inductors. External resistors are also needed to
set the output impedance and to match the IF output to the specified load resistance R
L
(see Fig.3).
Value includes losses due to the printed circuit board and balun.
Value is guaranteed only for the P
i(LO)
typ.
For a given RF input power, the value is the difference in the power measured at the IF output when the LNA is
switched on and when it is switched off.
This value is guaranteed within the temperature range
10 to +70
°
C.
Voltage gain is defined as the differential baseband output voltage (either at pins IA/IB or pins QA/QB) divided by the
differential input voltage at pins RXIIFA and RXIIFB.
Value refers to differential voltage at pins RXIIFA and RXIIFB (1 k
input impedance).
Value includes printed circuit board and balun losses.
