MAX2323 datasheet(4/14 Pages) MAXIM

Note 1: Devices are production tested for functionality at frequencies stated; 30 units from 3 independent wafer lots, when one lot

was at the upper process extreme, one lot was nominal, and one lot was at the lower process extreme, were characterized.

The resulting standard deviation therefore includes process variations. Data sheet limits are ±3

σ from the mean.

Note 2: Operation over this frequency range requires the ports to be rematched for the desired operating range. Performance at

various frequencies is indicated by the S-parameter data in Tables 3–7.

Note 3: Specifications are based on RBIAS = 20k

Ω. ICC for all LNAs (except HGHL) and mixers are inversely proportional to RRBIAS.

IIP3 can be traded for ICC by selecting other values of RRBIAS.

AC ELECTRICAL CHARACTERISTICS (continued)

(MAX2323 EV kit, FPLNAIN = 1960MHz, FCLNAIN = 881MHz, FIF = 110MHz, high-side LO, 50

Ω system, RRBIAS = 20kΩ,

RRLNA = 24k

Ω. Typical values are VCC = 2.75V, TA = +25°C. LO input power = -7dBm, LOW = 0V, HIGH = VCC, unless otherwise

noted.) (Note 1)
