SiGe Semiconductor Power Amplifier Delivers Industry-Leading Performance For Mobile Wimax
SiGe Semiconductor expanded its series of power amplifiers and RF front end modules with the release of the SE7262L. A 2.5GHz high-power amplifier targeted for the mobile WiMAX market, that delivers performance exceeding the spectral mask requirements outlined in IEEE 802.16e and WiMAX Forum specifications. The device delivers extremely high stability over the full temperature range, enabling manufacturers to support broadband wireless multimedia services in products for mobile computing applications without compromise to battery life. It is ideal for use in battery-powered applications, including USB accessories, PC cards, and embedded cards for laptop computers.
The new PA delivers more than 20% efficiency at +25.5 dBm output power while operating at 3.3V, which is the highest performance available while meeting worldwide spectral mask requirements. The combination of high output power, high linearity, exceptional efficiency and unequalled stability over temperature will enable systems that require low current for increased battery life and provide extremely reliable wireless link performance.
Before the SE7262L, available mobile WiMAX PAs often needed an increase in supply voltage in order to achieve higher output power. This approach required additional voltage regulation, increasing power consumption and cost to the system bill of materials. With the SE7262L, designers do not need this additional circuitry and voltage regulation. The SE7262L PA offers high levels of integration, featuring an on-chip power detector, step attenuator, and harmonic filter all in a compact 4x4x0.9mm package. This integration provides unequalled system performance and reduces overall footprint and bill of materials cost. The SE7262L offers industry-leading stability over temperature across the full temperature range of -40 to +85C, and it is fully input and output matched.
