in the frequency band of 4.2 to 4.4 GHz. How-
ever, radar altimeter receivers may be sensi-
tive to frequencies outside this range, and this
is the basis for the FAA's current reluctance to
wireless 5G wireless station deployment near
airports.
Designers Notebook:
Design for Test, Part 2 E
Current generations for PCB designs have
increased in complexity. e product devel-
oper and assembly service provider, whether
in-house or outsourced, must consider man-
ufacturing efficiency, throughput, and pro-
cess yield. While design for manufacturing
is an absolute necessity for controlling
manufactur ing costs, design to accommo-
date product testing does need attention as
well. e primary concern is to ensure that the
end product will perform reliably without
compromise.

Connect the Dots: The PCB Design Secret
Sauce for RF Applications E
Design and manufacture of PCBs for radio fre-
quency (RF) technology is a unique animal.
RF had been considered a niche, thought of
only in terms of television broadcasts, com-
mercial airline phones, and military radar
systems. Now, light industrial and consumer
applications ranging from remote meter read-
ing to home security systems are just the tip of
the RF iceberg.
