280MHz to 450MHz Programmable

ASK/FSK Transmitter

Typical Operating Characteristics (continued)

(Typical Application Circuit, 50I system impedance, VDD5 = VGPOVDD = VAVDD = VDVDD = VPAVDD = 2.1V to 3.6V, fRF = 280MHz to

450MHz, fXTAL = 16MHz, TA = -40NC to +125NC, unless otherwise noted. Typical values are at VDD5 = VGPOVDD = VAVDD = VDVDD

= VPAVDD = 2.7V, TA = +25NC, PA matched for optimum output power, unless otherwise noted. Supply current and output power are

greatly dependent on board layout and PAOUT match.)
