These devices are designed primarily for high–efficiency UHF and VHF detector
applications.They are readily adaptable to many other fast switching RF and digital
applications.They are supplied in an inexpensive plastic package for low–cost,
high–volume consumer and industrial/commercial requirements.They are also
available in a Surface Mount package.
