AC ELECTRICAL CHARACTERISTICS

(MAX2769 EV kit, V

= 2.7V to 3.3V, T = -40°C to +85°C, PGM = GND. Registers are set to the default power-up states. LNA input

is driven from a 50Ω source. All RF measurements are done in the analog output mode with ADC bypassed. PGA gain is set to 51dB

gain by serial-interface word GAININ = 111010. Maximum IF output load is not to exceed 10kΩ || 7.5pF on each pin. Typical values

are at V

= 2.85V and T = +25°C, unless otherwise noted.) (Note 1)
