SE5012T: 5 GHz Front-End Module with Power Detector
Applications
5 GHz WLAN (IEEE 802.11a/g/n)
Access points, PCMCIA, PC cards
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.
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.
For wireless LAN applications, the device meets the requirements
of IEEE 802.11a and delivers approximately +17 dBm of linear
output power at V
CC
= 3.3 V or 21 dBm at V
CC
= 5.0 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.
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.

Note 1:
Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
Note 2:
These are stress ratings only. Exposure to stresses beyond these maximum ratings for a long period of time may cause permanent damage to, or affect the reliability of the device.
Avoid operating the device outside the recommended operating conditions defined below.
CAUTION:
Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
