6 / 14 page – 6 – CXA3329ER Electrical Characteristics • Unless otherwise specified, the I/Q baseband input signals and local input signal use the conditions shown in the Electrical Characteristics Measurement Circuit and the control voltage and power saving pins are set to VCONT = 2.3V, PS = high. The local switching pin is left open (1/2 frequency division). • IF output impedance is 1k Ω. • Values measured with a Sony evaluation board. Note1) Set the control voltage so that the output power becomes –15dBm under the conditions shown in the Electrical Characteristics Measurement Circuit. Input the two tone signals of 570kHz, 200mVp-p and 630kHz, 200mVp-p to I-IX; and also input to Q-QX the two tone signals whose phases are deviated by 90 degrees from those signals. The ratio of the desired component and the 3rd order harmonic component of the outputs resulted from the above is measured, and the power level that is made by adding the half ratio to the desired component power level is labeled as the output IP3. See the figure on the next page.
