Modem Reference
Designs
The ISL837030 and ISL83740 Broadband Wireless Modem
Reference Designs support a wide range of modulation
orders and symbol rates.*
In both Reference Designs, sophisticated coding,
equalization, and symbol recovery techniques are employed,
resulting in robust wireless link performance.
The ISL837030 and ISL83740 Reference Designs support
high-capacity digital microwave radios with data rates up to
238Mbps (ISL83740) and 160Mbps (ISL837030). They
provide a flexible, high performance, economical solution for
fixed wireless applications.
* Differences between the ISL837030 and ISL83740 are marked in text as
needed. Also see
Release Notes on page 25
.
