WCDMA Quasi-Direct Modulator

with VGA and PA Driver

AC ELECTRICAL CHARACTERISTICS (continued)

MAX2395 EV kit, VCC = +2.7V to +3.3V, RBIAS = 12kΩ, VVGC adjusted to obtain maximum rated output power, and TA = -40°C to

+85°C. I/Q inputs driven differentially with low- impedance source based on 3GPP UpLink reference measurement channel

(12.2kbps), envelope level 1VP-P. Typical values are at VCC = +2.85V and TA = +25°C, unless otherwise noted. See Tables 1 and 3 for

register settings.) (Note 2)

Note 2: Guaranteed at TA = +25°C and TA = +85°C by production test, and guaranteed by design and characterization at TA = -40°C.

Note 3: VDH is the high voltage applied to the shutdown pin.

Note 4: Output power, linearity, noise power, and LO leakage specifications are met over this frequency range.

Note 5: Specifications valid for all output power levels, unless limited by thermal noise at lower output power levels.

Note 6: Guaranteed by design and characterization.

Note 7: Tested at 1MHz and 2MHz in the passband.
