MAX7058

315MHz/390MHz Dual-Frequency ASK Transmitter

AC Electrical Characteristics (continued)

(Typical Operating Circuit, 50Ω system impedance, VAVDD = VDVDD = VPAVDD = +2.1V to +3.6V, fRF = 315MHz or 390MHz,

TA = -40°C to +125°C, unless otherwise noted. Typical values are at VAVDD = VDVDD = VPAVDD = +2.7V, TA = +25°C, unless otherwise

noted. All min and max values are 100% tested at TA = +125°C, and guaranteed by design and characterization over temperature,

unless otherwise noted.)

Note 1: Supply current and output power are greatly dependent on board layout and PAOUT match.

Note 2: 50% duty cycle at 10kHz ASK data (Manchester coded).

Note 3: Guaranteed by design and characterization, not production tested.

Note 4: Dependent on PCB trace capacitance.
