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 VCC = 3.3 V or 21 dBm at VCC = 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.
