Handy RF solutions

RF Micro Devices (RFMD) has broadened its portfolio of 3G front ends with two new WCDMA/HSDPA power amplifiers: the RF3267 and the RF6266. The new PAs are designed to support multi-band, multi-mode 3G handsets and smartphones. The RF3267 is a Band 1, 1920 to 1980MHz, WCDMA/HSDPA PA with a digitally controlled low-power mode, which allows operation up to 19dBm with reduced current consumption. It features an integrated coupler, yet maintains a three by three by 0.9mm package size. By maintaining pin-for-pin compatibility with the previous generation PA, the new device helps manufacturers to shrink handset RF sections, supporting more compact, thinner devices.

With a similar feature set and package size, the RF6266 WCDMA/HSDPA PA can operate in either Band 5, 824 to 849MHz, or Band 8, 880 to 915MHz.

Used in combination, the two PAs provide a compact solution for multi-band, multi-mode 3G handset designs targeted at the North American or European Union markets.
