Description

The SE5005L is a 5 GHz Power Amplifier (PA) that offers high linear power for wireless LAN applications.

The SE5005L offers a high level of integration for a simplified design, which provides quicker time-to-market and higher application board production yield. The SE5005L integrates all matching elements, a 3.8 GHz notch filter, and a temperature-compensated, load-insensitive power detector with +20 dB of dynamic range.

For wireless LAN applications, the SE5005L meets the requirements of IEEE 802.11a and delivers approximately +18 dBm of linear output power. The SE5005L also features a linearity mode-control function to reduce current consumption at low power.

The SE5005L integrates the reference voltage generator, which allows for a true Complementary Metal Oxide Semiconductor (CMOS) compatible digital enable (EN) function to turn the PA on and off.

A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.
