D-CLUE increases the efficiency of mobile WiMAX terminal power amplifiers to 25%
Japan's D-CLUE Technologies has developed a power amplifier for mobile WiMAX terminal transmission circuits with up to 25% power added efficiency (PAE), which will begin sampling in October 2008.
The power added efficiency is as high as 25% when the amplifier transmit power is 24 dBm required by the mobile WiMAX terminal. At this time, 2.5% modulation accuracy (EVM) can be ensured, and high efficiency can be maintained even when applied to multi-value modulation such as 64-value QAM. In general, the power amplifier of a mobile WiMAX terminal has a low power addition efficiency of only about 10% to 15%. The reason is that the uplink uses OFDM, which requires high linearity of the power amplifier, and the result is that power added efficiency is sacrificed. Due to the low efficiency, there is a lot of unnecessary power consumption on the transmitting circuit, which may cause problems such as short battery driving time.
Imported bias control technology D-CLUE This product development power efficiency is 5 to 10 percentage points higher than the previous product, which can reduce the power consumption of the terminal transmission circuit. To improve power-added efficiency, the product uses a technique that optimizes the current bias and voltage bias inside the control amplifier in real time based on the transmitted signal. The company calls it "HiPAE technology." In a circuit in which OFDM modulation is applied to an uplink such as a mobile WiMAX terminal, the technology can reduce power consumption. The manufacturing process uses SiGe technology. In addition, some overseas manufacturers have also indicated that PAE has reached 25%, but most of them do not explicitly disclose the characteristics when using high-order modulation.
The power amplifier developed this time is called "DC12 Series". The power supply voltage is 3.3V, the output current is 300mA at an output power of 24dBm, and the gain is 30dB. There are two types for 2.5GHz frequency and 3.5GHz frequency. The package is a 4mm square QFN. The sample price is 1,000 yen. Mass production will be available in the first quarter of 2009.
The products will be supplied to major customers in the order of North America, Taiwan, and then Japan. In addition to the power amplifier for mobile WiMAX, D-CLUE will introduce this high-efficiency technology into LTE products and continue to develop it.
