Volume shipment of quadband power amp AWT6530 by Anadigics
RF IC chip maker Anadigics has announced production shipment of its quadband RF power amplifier which is designed to consume less power. The indium gallium phosphide based (InGaP-Plus) power amplifier chip AWT6530 is compatible with popular mobile phone chipset from vendors such as MediaTek, HiSilicon and Qualcomm and supports quad band GSM frequencies of 850 MHz, 900 MHz, 1800 MHz and 1900 MHz.
AWT6530 operates in two selectable power bias modes and also in shutdown mode to support dynamic power saving. Anadigics claims AWT6530 quad-band power amplifier delivers 40% power-added efficiency (PAE) operating in UMTS bands 1, 5, and 8 and 42% PAE in band 2.
The new power amplifier solutions called ProVantage solutions are designed for use with an external switch mode power supply (SMPS) to support average power tracking (APT), which further increases efficiency and reduces current consumption at low and medium operating powers, as per Anadigics.
AWT6530 with two independent amplification chains, Anadigics says it offer better amplification linearity for stable performance and high-throughput in 3G and 4G connections. On the size also these chips score well, the package measures 3x4x0.9 mm in dimensions. The RF matching optimized for output power, efficiency, and linearity in a 50-Ohm system
