Product Description
The SE5003L is a 5GHz power amplifier offering high
linear power for wireless LAN applications. The
SE5003L incorporates a power detector for closed
loop monitoring and control of the output power.
The SE5003L offers high integration for a simplified
design, providing quicker time to market and higher
application board production yield. The device
integrates the input match, the inter-stage match, the
output match, the power detector with 15dB of
dynamic range and a 3.8GHz notch filter. Only 6
external decoupling capacitors are required to
complete the design.
For wireless LAN applications, the device meets the
requirements of IEEE802.11a & 802.11n, and delivers
approximately 23dBm of linear output power at 5V.
The SE5003L integrates the reference voltage
generator. A 2.85V reference voltage on V
REF
is all
that is required to enable or disable the power
amplifier.
