SE5012T: 5 GHz Front-End Module with Power Detector

Applications

Description

The SE5012T is a 5 GHz front-end module offering high linear

power for wireless LAN applications. It incorporates a power

detector for control of the output power.

 5 GHz WLAN (IEEE 802.11a/g/n)

 Access points, PCMCIA, PC cards

The SE5012T offers a high level of integration for a simplified

design, providing quicker time to market and higher application

board production yield. The device integrates the input match,

inter-stage match, a temperature-compensated, load-insensitive

power detector with 20 dB of dynamic range, a 3.8 GHz notch

filter, a T/R switch, and LNA.

Features

 5 GHz front-end module with PA, LNA, and T/R switch

 Integrated power amplifier enable pin (VEN)

 Buffered, temperature-compensated power detector

 5 V or direct-to-battery operation

For wireless LAN applications, the device meets the requirements

of IEEE 802.11a and delivers approximately +17 dBm of linear

output power at VCC = 3.3 V or 21 dBm at VCC = 5.0 V.

 3% EVM, 64 QAM, 54 Mbps: +17 dBm @ 3.3 V or +21 dBm

@ 5 V

The SE5012T integrates the reference voltage generator, allowing

for a true 1.8 V CMOS compatible digital EN (enable) function to

turn the power amplifier on and off.

 30 dB typical gain

 Lead free, halogen-free, ROHS compliant QFN

(16-pin, 3 mm  3 mm  0.55 mm) package

(MSL1, 260 C per JEDEC J-STD-020)

A block diagram of the SE5012T is shown in

Figure 1. The device package and pinout for the 16-pin QFN are

shown in Figure 2. Signal pin assignments and functional pin

descriptions are described in Table 1.
