AdaptiveRF CMOS power amplifier architecture

The family of dual- and quad-band GSM/GPRS transmit modules uses a standard CMOS process and proprietary architecture that consistently outperform competing technology in performance, integration and cost, claims the company. The modules are targeted primarily at the high growth entry and ultra-low-cost (ULC) product segments in the emerging BRIC markets. Amalfi’s architecture integrates the power amplifier, controller, transmit and receive switch, filtering and all matching components into a 5.25×5.3mm package. The architecture allows the transmit module to achieve high efficiency over a broad output power range. In operation, where output power is dynamic and subject to non-ideal loads, these improvements result in a talk time increase of up to 40 percent. The modules are capable of withstanding a best-in-class 2kV ESD on all pins, including RF pins, making the device less susceptible to ESD damage during manufacturing, which results in better yields and overall lower cost. The devices are also capable of withstanding 8kV ESD on the antenna port, further lowering BOM as no additional ESD protection is required on the phone to meet industry standards.
