“…The PA can be used as a discrete component in the radio frontend circuit designs or as a building block for a dual-band FEM. With a dual-band switch-plexer or switch-LNA similar to the design presented in [3], a dual-band 802.11ac FEM can be easily realized in a 2-chip design as shown in Fig. 3.…”

“…All these unique features simplify the front-end circuit design of 802.11 a/b/g/n/ac WLAN radios. With a dual-band switchplexer or switch-LNA [3], a complete dual-band front-end module can be constructed with just two integrated circuit building blocks, the dual-band power amplifier described above, and a dual-band switch-plexer or switch-LNA. …”

A highly integrated SiGe BiCMOS PA is presented that enables the emerging high throughput 802.11ac WLAN applications. The PA has two stages for the g-band and three stages for the a-band PA, and integrates matching circuitry, out of band rejection filters, power detectors, and bias controls in a 1.5 x 1.6 mm chip. The gband PA achieves 28 dB gain with 2% EVM at 18 dBm and 3% at 19.5 dBm output power. The a-band PA achieves 32 dB gain with 2% EVM at 18 dBm and 3% EVM at 19 dBm output power. The design is verified meeting not only the regulatory out-of-band emission requirements but also the linearity requirement of the emerging 256 QAM 802.11ac standard.Index Terms -WLAN 802.11ac high throughput power amplifier, dual-band PA, dual-band front-end module.
