SE2537L
5 GHz Power Amplifier with Power Detector
Applications
DSSS 5 GHz WLAN (IEEE802.11a)
Access Points, PCMCIA, PC cards
Product Description
The SE2537L is a 5GHz power amplifier offering high
linear power for wireless LAN applications.
It
incorporates a power detector for closed loop
monitoring and control of the output power.
The SE2537L offers extreme 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, a partial output match, the power detector with
20dB of dynamic range and a 3.2GHz notch filter.
Two external components are required to complete
the design.
For wireless LAN applications, the device meets the
requirements
of
IEEE802.11a
and
delivers
approximately 19.5dBm of linear output power.
For high performance applications, the SP1,2 ports
are available to connect an optional external capacitor
to enhance dynamic EVM performance.
Remark
Samples
Tape and Reel
Standard
The SE2537L bias control establishes the reference
voltage required for proper operation and allows
enabling and disabling of the power amplifier.
