Notes
1. Measured in baseband (at pin IOUT or pin QOUT) on a carrier at 2 MHz and 25 dBmV.
2. Quadrature error with respect to 90
°.
3. The differential input impedance of the IC is 34
in series with the IC pins which give an inductance of 5 nH.
For optimum performance, this inductance should be cancelled by a matching network. Coupling capacitors of 1 pF
give an acceptable result.
4. Gain = Vo(dB) Vi(dB) (see Fig.3). Gain for symmetrical RF input
5. Gain = Vo(dB) Vi(dB) (see Fig.3). Gain for asymmetrical RF input
