DATA SHEET SE5012T: 5 GHz Front-End Module with Power Detector Applications Description The SE5012T is a 5 GHz front-end module offering high linear 5 GHz WLAN (IEEE 802.11a/g/n) power for wireless LAN applications. It incorporates a power Access points, PCMCIA, PC cards detector for control of the output power. The SE5012T offers a high level of integration for a simplified Features design, providing quicker time to market and higher application board production yield. The device integrates the input match, 5 GHz front-end module with PA, LNA, and T/R switch inter-stage match, a temperature-compensated, load-insensitive Integrated power amplifier enable pin (VEN) power detector with 20 dB of dynamic range, a 3.8 GHz notch filter, a T/R switch, and LNA. Buffered, temperature-compensated power detector For wireless LAN applications, the device meets the requirements 5 V or direct-to-battery operation of IEEE 802.11a and delivers approximately +17 dBm of linear 3% EVM, 64 QAM, 54 Mbps: +17 dBm 3.3 V or +21 dBm output power at VCC = 3.3 V or 21 dBm at VCC = 5.0 V. 5 V The SE5012T integrates the reference voltage generator, allowing 30 dB typical gain for a true 1.8 V CMOS compatible digital EN (enable) function to Lead free, halogen-free, ROHS compliant QFN turn the power amplifier on and off. (16-pin, 3 mm 3 mm 0.55 mm) package A block diagram of the SE5012T is shown in (MSL1, 260 C per JEDEC J-STD-020) Figure 1. The device package and pinout for the 16-pin QFN are TM shown in Figure 2. Signal pin assignments and functional pin Skyworks Green products are compliant with descriptions are described in Table 1. all applicable legislation and are halogen-free.
