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.
IF output impedance is 1k
.
Set the L, C values between Pins 8, 9 and 11, 12 to resonate at f = 570MHz.
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.
