Single-Placement RF Front Ends Provide Scalable 2G Power Platform
RF Micro Devices, Inc. has released the RF7178 the cellular industry's first front end module to integrate a quad-band, class 12-compliant GSM/GPRS power amplifier, a pHEMT antenna switch and receive SAW filters. The RF7178 also offers full quad-band transmit performance (GSM850/EGSM900/DCS1800/ PCS1900) and four dedicated receive ports in a compact single-placement package. Both the transmit and receive paths are performance optimized to deliver a low-loss, high efficiency front end solution without requiring additional matching components. In addition, the company introduces the RF7177, a dual-band (EGSM900/DCS1800) front end module that is pin-to-pin compatible with the RF7178 and features a similar feature set integrating the pHEMT antenna switch and SAW filters. When combined, RFMD's RF7178 and RF7177 provide a scalable platform solution for handset manufacturers seeking advanced levels of integration, streamlined inventory management and minimal deployment of valuable RF design resources. Compared to traditional discrete implementations, the RF7178 and RF7177 each eliminate approximately ten component placements, thereby reducing assembly costs, improving line yields and lowering the costs associated with purchasing and managing inventory.
