AC ELECTRICAL CHARACTERISTICS (continued)
(EV kits to evaluate the MAX2351/MAX2354/MAX2358/MAX2359/MAX2530/MAX2531/MAX2357/MAX2538, f
894MHz, f
LO for all except GPS, 50Ω system impedance, V
power = -10dBm, T
7dBm, unless otherwise noted.) (Note 2)
Note 1: Guaranteed at T
Note 2: Minimum and maximum specs are guaranteed by design and characterization, unless otherwise noted.
Note 3: Operating over this frequency range requires the ports to be rematched for the desired operating frequency.
Note 4: Two-tone separation is 900kHz cellular, 1.25MHz for PCS, and 1MHz for GPS.
