CORPORATION
Description
Q-Tech’s voltage-controlled crystal oscillators (VCXO)
consist of a varactor diode and associated circuitry such as a
bipolar transistor or logic IC amplifier, logic output buffers
and/or logic divider stages, and a round AT high-precision
quartz crystal built in a wide selection of Dual-In-Line (DIP)
or Surface -Mount (SMT) hermetically sealed packages.
Q-Tech offers custom design VCXOs in SMT packages
(QT78, QT88) at 3.3 Vdc and 5.0Vdc up to 72MHz. Please
contact Q-Tech for details.
