Description The SE5023L is a 5 GHz power amplifier offering high linear power for wireless LAN applications. The SE5023L offers a high level of integration for a simplified design, providing quicker time to market and higher application board production yield. The device integrates all matching elements, a temperature compensated, load insensitive power detector with 15 dB of dynamic range and a 3.8 GHz notch filter. For wireless LAN applications, the device meets the requirements of IEEE 802.11ac and 802.11n, and delivers approximately +24 dBm of 802.11ac output power or +26 dBm of 802.11n output power at 5 V. A 2.85 V reference voltage on VREF is all that is required to enable or disable the power amplifier. A block diagram of the SE5023L is shown in Figure 1. The device pinout for the 20-pin QFN are shown in Figure 2. Signal pin assignments and functional pin descriptions are described in Table 1.
