Maxim Integrated MAX2771 - Typical Operating Characteristics

(MAX2771 EV kit, V
CC
= 2.7V to 3.3V, T
A
= -40°C to +85°C. Registers are set to the default power-up states. LNA input is driven from
a 50Ω source. LNA input has specied external matching circuit. All RF measurements are done in the analog output mode with ADC
bypassed. PGA gain is set to GAININ = 111010 except for IF lter response plots in which case it is set to GAININ = 000100. For IF lter
response plots, MIXPOLE = 1. Maximum IF output load is not to exceed 10kΩ||7.5pF on each pin. Typical values are at V
CC
= 2.85V
and T
A
= +25°C, unless otherwise noted.)
