AC ELECTRICAL CHARACTERISTICS
(MAX12005 EV Kit, V
set to 0dB, RF inputs matched to 75I, RF output loads = 75I. Typical values are at +3.3V and at T
noted.) (Note 1)
Note 1: Production tested at +25NC; guaranteed by design and characterization at -40NC and +85NC.
Note 2: To supply the specified input-voltage-detect levels requires the use of a voltage-divider comprised of 12.7kI and 1.02kI
Note 3: The common input gain step is set by analog control. All gain measurements have only one output connect to each input.
Note 4: Switch-to-switch gain match is defined as each switch to every other switch gain match. Each switch must be set up with
