Anadigics unveils new line of PAs for SMPS devices
The new line of power amplifiers are optimised for use with SMPS, including DC/DC converters and envelope tracking. By pairing these 2 state mode power amplifiers with SMPS, designers are able to achieve industry-leading average current consumption.
Anadigics, a provider of RF and mixed signal semiconductor products, has introduced a new series of power amplifiers (PAs), leveraging the Company’s third generation High-Efficiency-at-Low-Power (HELP)technology.
The new HELP3DC AWT663x series PAs are optimised for CDMA, WCDMA/HSPA, and LTE devices that include a switched-mode power supply (SMPS), DC/DC converter, or Envelope Tracking IC to control the PA supply voltage. In this kind of design, HELP3DC PAs provide the world-class average current consumption to help extend battery life in handsets, smart phones, tablets, netbooks, and notebooks.
“Anadigics continues to raise the bar for wireless power amplifier performance with the introduction of our new HELP3DC series, optimised for devices that include DC/DC converters in their RF power management strategy,” said Bruce Webber, director of marketing for wireless RF products at Anadigics. “This addition to our successful and industry-leading HELP product family provides RF designers with more options to achieve longer battery life, enabling mobile device users to experience the full potential of mobile broadband 3G and 4G services.”
SMPS and DC/DC converters allow handset designers to reduce the PA supply voltage, decreasing average current consumption under selected conditions. Anadigics’ HELP3DC PAs have two power modes for high efficiency across both low and high RF power levels from a single mode control input. These PAs also provide exceptionally low quiescent currents of less than 8 mA at 3.4 V.
The HELP3DC PAs are also LTE, WCDMA, HSPA, HSPA+ and CDMA/EVDO compliant. Anadigics says they have the best-in-class linearity (ACLR1) at 3.4 V and 1.8V control logic. The modules are optimised for RF designs that vary the PA supply voltage to reduce current consumption.
Using a HELP3DC series PA in combination with an external DC/DC converter gives designers additional options to reduce battery current consumption in both high power and low power modes. Envelope tracking designs modulate the PA supply voltage to match the demands of the input RF signal. In Envelope Tracking designs, HELP3DC PAs can provide world-class performance and efficiency.
The highly integrated modules features an RF coupler, internal voltage regulation, integrated DC blocks on RF ports and come in 3 mm x 3 mm x 1 mm packages.
