This paper describes 2×2 MIMO 802.11ac Stage 1 WiFi + BT combo SoC chip with integrated dual-band PAs, LNAs, T/R switches, as well as a power management unit. The measured RX sensitivity of OFDM54M is -77.5dBm/ -77dBm in 2.4GHz and 5GHz, respectively. With the proposed broadband TX architecture, a high output power of 17.5dBm for 802.11ac Stage 1(More)
