5 / 16 page +2.7V, Single-Supply, Cellular-Band Linear Power Amplifiers _______________________________________________________________________________________ 5 Note 1: Minimum and maximum values are guaranteed by design and characterization, not production tested. Note 2: PMAX is met over this frequency range at the ACPR limit with a single matching network. For optimum performance at other frequencies, the output matching network must be properly designed. See the Applications Information section. Operation between 750MHz and 1000MHz is possible but has not been characterized. Note 3: PAE is specified into a 50 Ω load, while meeting the ACPR requirement. Note 4: Time from logic transition until POUT is within 1dB of its final mean power. Note 5: Murata isolator as load with 20:1 VSWR any phase angle after isolator. Note 6: Noise power can be improved by using the circuit in Figures 1 and 2. Note 7: Harmonics measured on the evaluation kit, which provides some harmonic attenuation in addition to the rejection provided by the IC. The combined suppression is specified. AC ELECTRICAL CHARACTERISTICS—MAX2269 (continued) (MAX2269 EV kit, VCC = VPWR = V SHDN = +3.5V, fIN = 906MHz, CDMA modulation, SHDN = VCC, matching networks tuned for 887MHz to 925MHz operation, 50 Ω system, TA = +25°C, unless otherwise noted.)
