WARREN, NJANADIGICS, Inc. introduced a new generation of High-Efficiency-at-Low-Power (HELP) power amplifiers (PAs) for CDMA applications. The PAs are designed to eliminate the requirements for external voltage regulation, reducing bill of materials cost and PCB space. Measuring 3 mm by 3 mm the new CDMA PAs are footprint compatible with the Company's 4 mm by 4 mm CDMA PAs, thereby reducing time-to-market for new designs.
The ICs are manufactured using the company's InGaP-Plus technology, which integrates bipolar and field-effect transistor (FET) structures on the same InGaP GaAs die.
The AWT6307 targets the US cellular band, and the AWT6308 is for US PCS band. Efficiency is specified at 20% at +16 dBm and 40% at +28 dBm. These new PA modules offer low quiescent currents of 16 mA and leakage currents of less than 1 μA to further reduce power consumption and increase talk-time.
The new power amplifiers are offered in compact 3 mm by 3 mm by 1 mm modules and are designed for applications that require European Union's Restriction of Hazardous Substances (RoHS) solutions. The AWT6307 and AWT6308 maintain pin-to-pin compatibility with existing 4 mm by 4 mm amplifiers, offering up to 50% space savings.
The AWT6307 and AWT6308 are priced at $1.29 in quantities of 10,000 units. Samples are available now.
