ELECTRICAL CHARACTERISTICS

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: Specifications over the –40

°C to 85°C temperature range are

assured by design, characterization and correlation with statistical process

controls.

Note 3: Tests are performed as shown in the configuration of Figure 6. The

IF input transformer loss is substracted from the measured values.

Note 4: Power gain is defined here as the I (or Q) output power into a 4k

Ω

differential load, divided by the IF input power in dB. To calculate the

voltage gain between the differential I output (or Q output) and the IF

input, including ideal matching network, 10 • log(4k

Ω/50) = 19dB has to

be added to this power gain.

Note 5: If a narrow-band match is used in the 2xLO path instead of a 1:2

transformer with 240

Ω shunt resistor, 2xLO input power can be reduced

to –10dBm, without degrading the phase imbalance. See Figure 11 and

Figure 6.

Note 8: The typical parameter is defined as the mean of the absolute

values of the data distribution.
