The ‘02’ package is used to evaluate the WPS343724-02 hardware. The 4 watt device in the ‘02’ package has a limited temperature range of approximately 60°C. An earless flange or flange package is offered with better Tjc and can be used at much higher temperatures. Please consult the factory for your specific application. Through holes with a diameter of 20 mils are spread uniformly over the center pad for thermal relief and Figure 1 Evaluation board RF ground. It is recommended that via holes be placed nearby the DC bias connector to maintain ground continuity between the top layer 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. Biasing with quarter-wave stubs at the gate and drain are shown in Figure 1. The impedance of the quarter wave structures is cyclical with frequency. A RF short is observed at frequencies that are even multiples of quarter-wavelength and open impedance is observed at frequencies that are odd multiples of a quarter-wavelength. A 56 ohm resistor is added in series to the gate bias. The effective impedance is increased which reduces the risk of oscillations. The 56 ohm resistor is not shown in Figure 1. Through holes underneath the package is required to connect the top and bottom grounds and to improve thermal conductivity. The WPS343724-02 has a noise figure less 5.5 dB shown in Figure 2 and the supply current shown in Figure 3 is less than 1.3 A in small signal and increases to 1.43 A for an output power of 37 dBm. The RF drive level is increased incrementally and stopped when the gate leakage current of 11 mA is reached. Typical large signal gain response, shown in Figure 4, varies from 14 to 15 dB over the frequency range 3.4 to 3.7 GHz. The output IP3 response shown in Figure 5 uses a two tone separation of 20 MHz and 25 dBm per tone at 3.4, 3.5, 3.6 and 3.7 GHz.
