Skyworks Solutions Inc. introduces four linear power amplifiers for LTE and WCDMA applications. The fully matched surface mount SKY66001-11 (2110 to 2170 MHz), SKY66002-11 (1900 to 2025 MHz), SKY66005-11 (850 to 920 MHz) and SKY66008-11 (900 to 990 MHz) modules meet the stringent spectral linearity requirements of femtocell applications with high power-added efficiency. An integrated directional coupler eliminates the need for any external coupler.
