The present invention provides a PLL circuit, which can make convergence at a high speed and convert an IF signal into an RF signal, and a wireless mobile station with that PLL circuit. For example, a 10 Gigabit Ethernet transceiver may be used to support SONETSDH communications with or without G. Optionally, the granules of the invention may further include at least one catalyst andor at least one wax andor at least one resin andor at least one preferably non-isocyanate-reactive polymer. Therefore, the surface of the metal separator can be protected from exposure to the atmosphere and water vapor when the solid oxide regenerative fuel cell is operated at high temperature. With this method, the user may create the content systematically.
