VCC = 3.3V, EN = 2.9V, fIF = 250MHz, PIF = –7dBm, fLO = 1700MHz, PLO = –5dBm, fRF = 1950MHz, TA = 25°C. (Note 5)

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: Interval from the rising edge of the Enable input to the time when

the RF output is within 1dB of its steady-state output.

Note 4: Interval from the falling edge of the Enable signal to a 20dB drop

in the RF output power.

Note 5: R1 = R7 = 22.6

Ω, Z1 = Z7 = 100nH.

Note 6: Second harmonic distortion measured at fLO + fIF1 + fIF2.
