Page 4 of 8, Updated June 4, 2008 MMA-495933-Q5 4.9 – 5.9 GHz Linear Power Amplifier Preliminary Data Sheet June 2007 Application Note The measurements presented are recorded at Vdd=7.5 volts and Ids= 600 mA. The evaluation board layout is shown in Figure 1. Rogers 4003 is the choice for many RF board materials because of its high frequency response, temperature stability and low cost. The board height is 20 mils and the copper trace weight is 1 oz. Many through holes with a drill diameter of 12 mils are spread uniformly across the center pad for thermal relief and RF ground. It is recommended that via holes be placed nearby the DC bias connector to maintain ground continuity between the top and bottom ground planes. Mounting holes near the unit will help secure the board to the chassis, minimize ground current loops and improve thermal conductivity in the absence of sweat soldering the board to the chassis. The via hole design, shown in Figure 2, uses two via patterns that are interleaved; one is 5x5 and the other is 4x4; the finished via hole diameter is 9 mils. The pitch between holes is 25 mils. The simulated thermal impedance is less than 0.9°C/W. The PCB finish is nickel over copper with a gold flash. Please consult our factory to request s-parameters, Gerber file and samples. The MMA-495933-Q5 amplifier includes two built-in bias tees for gate control at QFN pin 10 and for drain control at QFN pin 22. In addition, the MMA-495933-Q5 has its own DC blocking capacitors. The breakdown voltage for the blocking capacitor is 22 VDC. The schematic for the evaluation board is shown in Figure 3. The evaluation board has two bias terminals; terminal P1 is for gate control and terminal P2 is for drain control. The gate control should be adjusted first before setting the drain. The typical gate voltage is -1.0 volts and the drain voltage is 7.5 volts. The bias current is approximately 600 mA with no RF applied. These bias conditions can vary with the application requirements; that is, setting lower current for low power or setting higher current for pristine performance.

Page 5 of 8, Updated June 4, 2008 MMA-495933-Q5 4.9 – 5.9 GHz Linear Power Amplifier Preliminary Data Sheet June 2007 Application Note (continued) The typical small signal gain response, shown in Figure 4, varies from 10 to 11 dB over the frequency range 4.9 to 5.9 GHz. The output IP3 response shown in Figure 5 uses a two tone separation of 20 MHz at 4.9 and 5.9 GHz. Notice that linearity of this amplifier is maintained at very low power levels which give rise to better signal to noise interference ratio. A block diagram of the WiMAX test setup is shown in Figure 6. The burst frame length is 141 symbols and the channel bandwidth is 3.5 MHz. A summary of the burst is shown in Figure 7. The measured EVM error is segmented into two sections. The SMU200A contributes about 0.5%, and the driver contributes about 0.3% to the total EVM. The EVM measurement includes the 0.8% error from the driver and source. The residual EVM error for the MMA-495933Q5 is 1.2% at burst power of 27 dBm.

Page 6 of 8, Updated June 4, 2008 MMA-495933-Q5 4.9 – 5.9 GHz Linear Power Amplifier Preliminary Data Sheet June 2007 Application Note (continued) The noise figure, shown in Figure 8, is less than 8.0 dB across the frequency range 4.9 to 5.9 GHz. The MMA-495933-Q5 includes a stability resistor that adds to the noise figure. The typical noise floor for an on-chip WiMAX modulator is -107 dBm per MHz. Assume that the total system gain is approximately 35 dB and the predriver stage used has a gain of 25 and noise figure of 5.5 dB. The noise floor to PA is -79 dBm per MHz. The noise floor at the output of the MMA-495933-Q5 is -68.5 dBm per MHz. This shows that sensitivity for this system is -29 dBm per 3.5 MHz for SNR = 34 dB. The MMA-495933-Q5 does not noise limit the system performance.
