DESCRIPTION:
Cernex CVG Series varactor tuned Gunn oscillators combine with
a proprietary circuit design capability and the experience with
either GaAs or InP Gunn diodes to cover the frequency range of
18 to 110 GHz in seven waveguide bands. The oscillators are especially
designed for high output power, wide varactor tuning range, mechanically
tuning ability and low AM/FM noise characteristics. The DC power
is applied via a low pass EMI filter, while a female SMA connector
is utilized for the varactor tuning voltage. The tuning rate can
be as high as 50 MHz. The oscillators are ideally suited for FMCW
transceivers, AFC loops and phase locked systems. The oscillators
can be supplied with optional integrated isolator, voltage regulator
and temperature heater. While waveguide is the standard interface,
the oscillators are available with coaxial interface as an option.
