AC ELECTRICAL CHARACTERISTICS (continued)

(MAX2116/MAX2118 EV kits, VCC = +4.75V to +5.25V, GC1 and GC2 set for maximum gain, GND = 0V, IOUT = QOUT = 800mVP-P

(MAX2116), loaded with 1kΩ IOUT± = QOUT± = 590mVP-P differential (DL = 0, MAX2118), IOUT± = QOUT± = 1VP-P differential (DL

= 1, MAX2118), loaded with differential 2kΩ. Baseband LPF BW = 33MHz, fRFIN = 2175MHz. For default register values, see the

Serial Interface and Control Registers section. TA = +25°C to +85°C. Typical values are at VCC = +5V, TA = +25°C, unless otherwise

noted.) (Note 1)

Note 1: Parameters are production tested at TA = +25°C and +85°C; limits called out at 0°C are guaranteed by design and charac-

terization and are not production tested.

Note 2: GCI gain control is guaranteed over this voltage range. 0.75V corresponds to maximum gain and 2.6V corresponds to

minimum gain.

Note 3: RF front-end specification met at this output level.

Note 4: The VTUNE ADC transfer curve has been tailored to that of the VCO tuning curve.

Note 5: Input IP3 test conditions: VGC1 set to provide 800mVP-P (MAX2116), 1VP-P differential (MAX2118, DL = high), 0.59VP-P dif-

ferential (MAX2118 DL = low) baseband output when mixing down a -25dBm tone at 2175MHz to 5MHz baseband, with

VGC2 = 00000. Two tones at -18dBm each are applied at fLO -100MHz and fLO -195MHz; IM3 tone at 5MHz is measured at

baseband but is referred to RF input.

Note 6: Input IP2 test conditions: VGC1 set to provide 800 mVP-P (MAX2116), 1VP-P differential (MAX2118, DL = high), 0.59VP-P dif-

ferential (MAX2118 DL = low) baseband output when mixing down a -25dBm tone at 2175MHz to 5MHz baseband, with

VGC2 = 0.75V. Two tones at -25dBm each are applied at fRF = 925MHz and fRF = 1245MHz; IM2 tone at fLO - 5MHz is mea-

sured at baseband but is referred to RF input.

Note 7: These parameters are guaranteed by design and characterization, and are not production tested.
