Description
Crystals in the HFX4 Series are rugged,
very high frequency miniature AT-cut
resonators housed in cold-welded tubu-
lar packages. Patented Tab-Mesa Tech-
nology (TmT), proprietary to SaRonix,
is used to achieve fundamental resona-
tors to 250 MHz.

Typical Crystal Parameters:Manufacturing
HFX4 units are photolithographically
produced on large wafers in a highly
automated facility. Stringent process con-
trol on custom equipment results in reso-
nator thicknesses down to 0.00033"
(0.0084 mm). A proprietary combination
of crystal and holder designs results in a
finished crystal unit that is both rugged
and extremely reliable.
Crystals are 100% leak checked and en-
vironmentally stress tested to assure reli-
able operation.
Ordering and Samples
The use of array processing enables large
quantities of crystals to be produced eco-
nomically. Smaller quantities ordered to
unique frequencies may involve a setup
charge. To minimize cost, it is suggested
that evaluation samples be selected from
the large number of frequencies that have
already been produced. Please contact
SaRonix for assistance.
