AC ELECTRICAL CHARACTERISTICS (continued)

(MAX2371/MAX2373 EV Kits, VCC = 2.65V to 3.3V, RX_EN = high, RSET = 1.1kΩ, TA = -40°C to +85°C. Typical values are at VCC =

2.775V; for MAX2371 fRF = 150MHz, for MAX2373 fRF = 850MHz to 940MHz; TA = +25°C, unless otherwise noted.) (Note 1)

Note 1: Parameters over temperature and supply voltage range are guaranteed by design and characterization, unless otherwise noted.

Note 2: Operation outside these frequency bands is possible but has not been characterized. See Typical Operating Characteristics.

Note 3: Measured with external matching network.

Note 4: fIN1 = 150MHz, fIN2 = 150.1MHz, PIN = -30dBm for both tones (MAX2371).

Note 5: fIN1 = 900MHz, fIN2 = 900.1MHz, PIN = -30dBm for both tones (MAX2373).

Note 6: Parameters are guaranteed by production test.
