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 7.

Note 4: On each of the four baseband inputs BBPI, BBMI, BBPQ and

BBMQ.

Note 6: Maximum value within – 1dB bandwidth.

Note 7: An external coupling capacitor is used in the RF output line.

Note 8: At 20MHz offset from the LO signal frequency.

Note 9: At 20MHz offset from the CW signal frequency.

Note 10: At 5MHz offset from the CW signal frequency.

Note 11: RF power is within 10% of final value.

Note 12: RF power is at least 30dB lower than in the ON state.

Note 13: Baseband is driven by 2MHz and 2.1MHz tones. Drive level is set

in such a way that the two resulting RF tones are –10dBm each.

Note 14: IM2 measured at LO frequency + 4.1MHz.

Note 15: IM3 measured at LO frequency + 1.9MHz and LO frequency +

2.2MHz.

Note 16: Amplitude average of the characterization data set without image

or LO feed-through nulling (unadjusted).

Note 17: The difference in conversion gain between the spurious signal at

f = 3 • LO – BB versus the conversion gain at the desired signal at f = LO +

BB for BB = 2MHz and LO = 2GHz.
