ANADIGICS' new ProEficient power amplifiers use the company's proprietary InGaP-PlusTM technology and patented design architecture to deliver an unparalleled calling experience for low-power modes while extending data usage time in high-power modes. This differentiation technology also increases the integration of dual-band 3G and 4G applications and reduces 3D space requirements.
Jerry Miller, vice president of wireless mobile products at ANADIGICS, said: "Modern 4G smartphones give users a very high data transfer speed comparable to many wired broadband connections. However, the increase in 4G data usage will result in power consumption. The high battery life of smartphones and tablets is shortened. ANADIGICS' new dual-band ProEficient power amplifiers deliver the industry's highest efficiency at all power levels and are available in a highly integrated, small package that extends battery life and extends battery life. Made a slim design."
ANADIGICS' dual-band ProEficient power amplifiers use two separate amplifier chains to provide outstanding performance for each frequency band. These power amplifiers deliver industry-leading efficiency in both high and low power modes without the need for DC-DC converters to maximize battery life in 4G devices. At the same time, ProEficient power amplifiers are optimized for use with Average Power Tracking (APT) technology to further increase efficiency and reduce current consumption at low to medium operating power. By integrating the common frequency band combination with the built-in voltage regulator in a 3 mm × 4 mm package, these power amplifiers that extend battery life save valuable PCB board space.
