Output Power versus PCNTRL Voltage DESIGN AND APPLICATIONS INFORMATION The MRFIC2403 is a two-stage power amplifier designed using Motorola's MAFET planar, refractory gate MESFET IC process. The RF MESFETs are power, depletion mode devices and, therefore, require negative bias on the MESFET gates. For class B operation, -1.0 Vdc is applied to VG1 and -2.0 Vdc is applied to VG2. Class A biasing will yield slightly higher gain and 1.0 dB compression point and can be accomplished by adjusting the bias on VG1 for IDQ1 = 24 mA and VG2 for IDQ2 = 96 mA. Where negative voltages are not already available, Motorola's MC33128 Power Management IC can produce -2.5 Vdc from a single positive supply. The device is capable of better than +23 dBm saturated output power in the 2.4 to 2.5 GHz ISM band with the output matching circuit shown in Figure 1. The device can be operated at other frequencies in the 2.0 GHz to 3.0 GHz range with this circuit but performance can be improved with tuning for the specific frequency of use. Input matching is provided on chip. This circuit provides the best gain, saturated output power and efficiency tradeoff. Saturated operation has the advantage of best efficiency with less variation in performance over frequency and temperature. Operation in saturation is acceptable for constant envelope modulation schemes such as 2 and 4 level FM as specified for frequency hopping (FHSS) radios in the proposed IEEE 802.11 PHY layer specification. For direct sequence MOTOROLA RF DEVICE DATA (DSSS) IEEE 802.11 operation, where differential binary phase shift keying (DBPSK) and differential quadrature phase shift keying (DQPSK) are specified, the amplifier will have to be "backed off" from saturation by 5.0 dB or more to avoid spectral regrowth. Care must be taken in the layout of the circuit and controlled impedance lines must be used at the RF pins. Capacitive bypassing as shown in the Applications Circuit must be implemented as close to the chip as possible to avoid amplifier instability. Additionally, the supply voltage should be supported by sufficient "stiffening" capacitance, typically electrolytic or tantalum bypass capacitors, to eliminate noise from digital circuits. Output power control is accomplished by varying the voltage on the PCNTRL pin. 0 Vdc gives minimum output and reduces the current drawn by the amplifier to the quiescent value. The amplifier can be put into "sleep" mode by decreasing the voltage on the gate bias pins to -3.0 Vdc and the current drain is reduced to a few hundred microamps.
