Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

DC ELECTRICAL CHARACTERISTICS

(MAX3507 EV Kit, VCC = +4.75V to +5.25V, VGND = 0, VTXEN = VSHDN = VCC, D7 = 1, TA = -40°C to +85°C, unless otherwise speci-

fied. No input signal applied. A 4:1 (300Ω to 75Ω) impedance ratio balun is connected to differential output ports and balun output is

terminated into a 75Ω load. Typical parameters are at VCC = +5.0V, TA = +25°C.) (Note 1)
