AC ELECTRICAL CHARACTERISTICS
(MAX2235 Evaluation Kit, GC = unconnected, P
T
Note 1: Guaranteed by design and characterization.
Note 2: For optimum performance at a given frequency, design the output matching network for maximum output power.
Note 3: Gain is monotonic with V
Note 4: 0.068µF capacitor from RAMP to REF. Time is measured from SHDN low-to-high transition to +29dBm output power, or
Note 5: Harmonics measured on the evaluation kit, which provides some harmonic attenuation in addition to the rejection provided
