Power Amplifier Modules Save Space, Cut Time To Market In Handset Applications

The latest generation of RF Micro Devices’ PowerStar family of power amplifier (PA) modules is the RF3198 dual-band PA, which targets the major growth areas in the cellular handset market, including entry-level and replacement handsets, GSM/EDGE handsets, and 3G multimode handsets. RFMD also announced that its RF3161 quad-band EDGE PAM is now sampling to customers.

The improved isolation, harmonic performance, and cross-band coupling of the RF3198 reduce rf complexity and increase design flexibility related to antenna and switch selection. Additionally, these improvements simplify calibration and increase manufacturing yields, which speeds time to market and reduces total cost of ownership. The device is pin-for-pin compatible with RFMD’s RF3146 family of PowerStar PA modules. The RF3198 comes in a low-cost 7- by 7- by 0.9-mm package and is fully RoHS-compliant. It is available now and costs $0.98 in quantities of 1 million.

The high level of integration in the RF3161 combines with a 6- by 6- by 1-mm package to deliver the smallest EDGE PA solution in its class, according to RFMD. By limiting the number of external components and eliminating external routing during customer implementation, the RF3161 reduces manufacturers’ total bill-of-materials costs and reduces time to market. Additionally, the RF3161 uses RFMD’s PowerStar integrated power control architecture to provide state-of-the-art GMSK efficiencies without impacting EDGE performance.
