QuinStar Technology’s QPL series of Phase Locked Oscillators are
available over the frequency range of 26 to 150 GHz. These sources are produced using one
of several possible methods of generating the microwave or millimeter wave power, and
phase-locking the source to an appropriate reference oscillator. Depending on the
frequency of operation, QuinStar’s series QPL Phase-Locked Sources are created using
one or more of the following oscillators:
(a) Microwave
GaAsFET or SiGe Device-based Dielectric Resonator Oscillator
(b) Microwave
Voltage Controlled Oscillator
(c) Microwave
Oscillators followed by Active or Passive Frequency Multipliers
(d) Gunn Diode or
IMPATT diode-based Oscillators
Also,
phase-locking of the oscillator to a reference source is achieved by employing the most
suitable and optimal technique from a variety of approaches and/or architectures. |
Each
design approach has unique advantages and features that allow QuinStar to provide an
optimal Phase-Locked Source for virtually any application.
QuinStar can integrate high
power amplifiers to achieve maximum power levels available at a given frequency.
QuinStar’s PLO’s are
available with either internal or external crystal references. Internal crystal oscillator
frequencies can range from 5 MHz to 150 MHz. Synthesizers and special-purpose Phase-locked
oscillators are also offered as customized products.
These sources can be provided
with varying degrees of packaging and integration, ranging from miniature modules to
stand-alone Instrumentation-style products with complete power supplies, and in
customer-specific outlines. |
