The Development Of 3G Phone Makes The Supply Of Power Amplifier Short
The power amplifier, which is heavily needed by the 3G cell phone
, is always facing the problem of short supply from the year of 2009. There are so many reasons make the demand of this component increase and the supply can not meet the demand, such as the popularization of low cost phones and Smart Phones. This problem must be noted by the practitioners when they are preparing to purchase the materials, especially in the following years. It is predicated the 3G phone will develop rapidly in the following years. Its shipment will surpass the GSM phone in this year; its shipment will be very considerable in the year of 2013, which can reach one billion.
Compared with the 2G phone which only needs one, the 3G phone needs more than three power amplifiers. Some phones add the WiFi function, so they need four to five of this material, for example, the iPhone 3GS uses 4. Therefore, some experts maintain that the expansion of the 3G phone market will cause the shortage of power amplifier last longer. Generally, the 3G phone has high requirement for the power amplifier's performance. The GaSA processing is more efficient and energy saving. Compared with the silicon processing which has thirty percent of energy efficiency, the GaAs processing has forty five percent of energy efficiency. Therefore, the GaAs processing is always popular. Actually, about ninety percent of the 3G phones' power amplifiers apply the GaAs processing.
Most of the Practitioners use the GaAs processing in the market; many of them constantly released their new products in the recent years. However, the expansion of GaAs power amplifier can not meet the demand, some practitioners are trying to apply the CMOS processing. Actually, if the CMOS processing is popularized, the supply of the power amplifier will not be limited by the capacity. The related integrated circuit is
