PA RAMP 0 (NO RAMP) PA RAMP 1 (256 CODES PER BIT) PA RAMP 2 (128 CODES PER BIT) The PA output current and, consequently, the output power are programmable over a wide range. The PA configuration is shown in Figure 38. The output power is set using Register 2, Bits[DB18:DB13].

PA Ramping Settings RFOUT PA Bias Currents REGISTER 0, BIT DB27 RFGND FROM VCO Figure 38. PA Configuration The PA is equipped with overvoltage protection, which makes it robust in severe mismatch conditions. Depending on the application, users can design a matching network for the PA to exhibit optimum efficiency at the desired radiated output power level for a wide range of antennas, such as loop or monopole antennas. See the LNA/PA Matching section for more information. PA Ramping The PA_BIAS bits (Register 2, Bits[DB12:DB11]) facilitate an adjustment of the PA bias current to further extend the output power control range, if necessary. If this feature is not required, the default value of 9 A is recommended. If output power greater than 10 dBm is required, a PA bias setting of 11 A is recommended. The output stage is powered down by resetting Register 2, Bit DB7 to 0. MODULATION SCHEMES The ADF7021-V supports 2FSK, 3FSK, and 4FSK modulation. The implementation of these modulation schemes is shown in Figure 40. When the PA is switched on or off quickly, its changing input impedance momentarily disturbs the VCO output frequency. This process is called VCO pulling, and it manifests as spectral splatter or spurs in the output spectrum around the desired carrier frequency. Some radio emissions regulations place limits on these PA transient-induced spurs (for example, the ETSI EN 300 220 regulations). By gradually ramping the PA on and off, PA transient spurs are minimized. The ADF7021-V has built-in PA ramping configurability. As Figure 39 illustrates, there are eight ramp rate settings, defined as a certain number of PA setting codes per one data bit period. The PA steps through each of its 64 code levels but at different speeds for each setting. The ramp rate is set by configuring Bits[DB10:DB8] in Register 2.

If it is enabled/disabled by the Tx/Rx bit (Register 0, Bit DB27), it ramps up and turns hard off. Rev.
