Product Description
The SE5503A is a complete 802.11a/b/g/n WLAN RF
front-end module providing all the functionality of the
power amplifiers, filtering, power detector, T/R switch,
diplexers and associated matching. The SE5503A
provides a complete 2.4 GHz and 5 GHz WLAN RF
solution from the output of the transceiver to the
antenna in an ultra compact form factor.
Designed for ease of use, all RF ports are matched to
50
Ω to simplify PCB layout and the interface to the
transceiver RFIC. The SE5503A also includes a
transmitter power detector with 20 dB of dynamic
range for each transmit chain. Each power amplifier
has a separate digital enable control for transmitter
on/off control. The power ramp rise/fall time is less
than 0.7
μsec.
The device also provides a notch filter from 3.260-
3.267 GHz and 3.28-3.89 GHz prior to the input of
each 2.4 GHz and 5 GHz power amplifiers,
respectively.
The SE5503A packaged in 4mm x 4mm x 1.0mm,
Halogen free, Lead free, ROHS compliant, MSL 3
LGA package.
