• Custom design capability
De s c rip t io n
The VH series is fundam ental PIN varactor tuned oscillators. The negative resistance is m ade with
a silicon transistor. Frequency oscillation is given by the varactor acting as a variable capacitor allowing
frequency tuning range. TEMEX' Hi-Rel voltage controlled oscillators are m anufactured with ceram ic
substrate and thin film technology to guarantee excellent perform ances and repeatability unit to unit.
Discrete com ponents such as transistors, varactors and capacitors are directly bonded on the ceram ic
while resistors are laser trim m ed. Tuning coil is etched by design on the substrate and allows the
frequency adjustm ent by length selection. They are particularly suited for down converter and phase
locked loop application.
Packages are optim ized for herm eticity and reliability purposes. They are proposed in DIL, Flat Pack or
Surface Mount packages.
Their rugged construction is particularly recom m ended for any use in strong m ilitary environm ent.They
are m anufactured under MIL STD 883 to m eet higher reliability perform ances.
