SKY65006-348LF Functional Block Diagram 27 dB small signal gain Description 802.11g linear power: +18 dBm (includes integrated filter loss) The SKY65006-348LF-348LF is a linear, high-gain two-stage 802.11b mask-compliant power: +21 dBm (includes integrated power amplifier with integrated output power detector and second filter loss) harmonic (F2) filter, designed for low voltage operations. This 802.15.4 mask-compliant power: +15.4 dBm (includes device is manufactured on an advanced Gallium Arsenide (GaAs), integrated filter loss) Heterojunction Bipolar Transistor (HBT) process. The device is Low-cost 16-pin QFN (3 x 3 x 0.75 mm) plastic package designed for power amplifier applications in WLAN, ZigBee, and spread spectrum systems from 2.4 to 2.5 GHz. The amplifier is Lead (Pb)-free, and RoHS-compliant packaged in a QFN-16, 3 x 3 x 0.75 mm package. The Skyworks SKY65006-348LF is a high-performance 2-stage TM Skyworks Green products are compliant with InGaP power amplifier designed for 2.4 to 2.5 GHz ISM, all applicable legislation and are halogen-free. IEEE 802.11b, 802.11g WLAN and ZigBee band applications. The For additional information, refer to Skyworks SKY65006-348LF is a high-efficiency linear amplifier designed for TM Denition of Green , document number single 3.3 V supply operation, requiring no input and output SQ040074. matching components for 50 operation. This device also includes an internal power detector and integrated harmonic filter for reduced PC board component count. The integrated low pass filter is also highly effective in reducing harmonics at their source by localizing harmonic rejection to a tiny portion of the PA chip. This significantly reduces the risk of radiation from a high order filter design external to the amplifier. Filtering of harmonics in this way can eliminate the need for an external shield over the PA, and reduces overall cost. A functional block diagram is provided in Figure 1.
