AC ELECTRICAL CHARACTERISTICS (continued)

(MAX2130 EV kit, V

= +4.75V to +5.25V, RBIAS

= 15kΩ ±1%, f

= 500MHz, Z

= 75Ω. Typical values are at V

= +5V,

= +25°C, unless otherwise noted.) (Note 1)

Note 1: Specifications are guaranteed by design and characterization, except for gain which is production tested.

Note 2: Specifications are guaranteed over the operating frequency range.

Note 3: Operation possible with V

= +3.5V. See Typical Operating Characteristics.

Note 4: Two tones at 500MHz and 506MHz, -20dBm per tone.

Note 5: Two tones at 500MHz and 550MHz, -20dBm per tone.

Note 6: Output load has worst-case 6dB return loss.
