M18L
Description
The M18L is designed to be used in wireless systems that
are targeted for low-cost/high volume applications. It is a
hybrid mixer utilizing the best of Alpha's semiconductor,
circuit design and manufacturing capabilities. A custom
silicon MMIC is complimented by a rugged thick-film
ceramic circuit which doubles as the surface mount
package. Wrap-around stress relieving leads ease
installation and inspection as well as solve thermal
expansion mismatch problems.
