Introduction

The SKY65006-348LF-348LF is a linear, high-gain two-stage power amplifier with integrated output power detector and second harmonic (F2) filter, designed for low voltage operations. This device is manufactured on an advanced Gallium Arsenide (GaAs), Heterojunction Bipolar Transistor (HBT) process. The device is designed for power amplifier applications in WLAN, ZigBee, and spread spectrum systems from 2.4 to 2.5 GHz. The amplifier is packaged in a QFN-16, 3x3x0.75 mm package.

The SKY65006-348LF is a high-performance 2-stage InGaP power amplifier designed for 2.4 to 2.5 GHz ISM, IEEE 802.11b, 802.11g WLAN and ZigBee band applications. The SKY65006-348LF is a high-efficiency linear amplifier designed for single 3.3 V supply operation, requiring no input and output matching components for 50 Ω 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.
