DESCRIPTION

Avantek Octave Band Series YIG-tuned fundamental transistor
oscillators are compact and lightweight and are cost-effective
for commercial instrument applications.
They are built using the same Avantek thin-film construction
and hermetic packaging that has proven itself ultimately reliable
under severe military and aerospace environmental conditions.
This family of oscillators is designed for wideband applications
in receivers and instruments where tuning linearity and spectral
purity are crucial.
They make ideal local oscillators for frequency-agile receivers
and spectrum analyzers and are excellent as signal sources for
microwave sweep generators and synthesizers.
The tuning curves (I

tuning vs. Fout) for this series of YTO's are

linear and will deviate from the ideal straight line only
± 0,05% to ± 0,2% (typically).

The power output remains flat within ± 1.5dB to ± 3.0dB over
the entire tuning range
These oscillators have compatible tuning port characteristics of
20 MHz/mA and 5 kHz bandwidth up to 12.4 GHz.
This helps to simplify the design of multiband equipment and
minimizes the number of current drives necessary.
All Octave Band Series oscillators have a low inductance FM
tuning in addition to the main tuning coil.
This coil is in close proximity to the YIG sphere and is used to
fine-tune the oscillator frequency, to phase lock the YTO or to
frequency modulate the output signal.
The sensitivity of this port is much less than that of the main
tuning coil, but it has a much wider 3 dB bandwidth and permits
input modulation or control signals to deviate the output
frequency by as much as 15 to 100 MHz at a rate up to 1 MHz
