AC ELECTRICAL CHARACTERISTICS (continued)
(MAX2338 EV kit, V CC = +2.7V to +3.3V, f PLNAIN = f PMIXIN = 1930MHz to 1990MHz, f CLNAIN = f CMIXIN = 869MHz to 894MHz, f IF =
183MHz, high side LO, LO/2 = LOW. All ports matched to 50 Ω, R
RLNA = R RBIAS = 24k Ω, T
A = -40°C to +85°C. Typical values are at
T A = +25°C, V CC = +3.0V, unless otherwise noted.)
Note 1: Operation over this frequency range may require the ports to be rematched for the desired operating frequency.
Note 2: MIN guaranteed by production test, MAX guaranteed by design and characterization.
Note 3: Guaranteed by design and device characterization.
Note 4: Two-tone IIP3. Tested at f
RF1 = 880MHz, f RF2 = 880.9MHz, and power = -25dBm/tone.
Note 5: Two-tone IIP3. Tested at f RF1 = 1960MHz, f RF2 = 1961.25MHz, and power = -25dBm/tone.
Note 6: F LO = 1064MHZ, f RF1 = 887.8MHz at -30dBm, f RF2 = 881MHz at -100dBm. Performance is measured as P IF due to
RF1 - P IF due to RF2.
Note 7: F LO
= 2143MHz, f
RF1
= 2051.5MHz at -35dBm, f
RF2
= 1960MHz at -100dBm. Performance is measured as P
IF
due to
RF1 - P IF due to RF2.
