M38L
Description
The M38L is designed to be used in wireless/VSAT
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.
