AC ELECTRICAL CHARACTERISTICS (DOWNCONVERTER OPERATION) (continued)

(MAX2041 Typical Application Circuit, VCC = +4.75V to +5.25V, RF and LO ports are driven from 50Ω sources, PLO = -3dBm to

+3dBm, PRF = 0dBm, fRF = 1700MHz to 3000MHz, fLO = 1900MHz to 3000MHz, fIF = 200MHz, fLO > fRF, TC = -40°C to +85°C,

unless otherwise noted. Typical values are at VCC = +5V, PRF = 0dBm, PLO = 0dBm, fRF = 1900MHz, fLO = 2100MHz, fIF = 200MHz,

TC = +25°C, unless otherwise noted.) (Note 1)

Note 1: All limits include external component losses. Output measurements taken at IF port for downconverter and RF port for

upconverter from the Typical Application Circuit.

Note 2: Compression point characterized. It is advisable not to continuously operate the mixer RF or IF input above +15dBm.

Note 3: Measured with external LO source noise filtered so the noise floor is -174dBm/Hz. This specification reflects the effects of all

SNR degradations in the mixer, including the LO noise as defined in Maxim Application Note 2021.

Note 4: Refer to the MAX2043 for improved LO leakage of -52dBm typical.
