VCO.
DESCRIPTION
The BB148 is variable capacitance
diode, fabricated in planar
technology, and encapsulated in the
SOD323 very small plastic SMD
package.
The excellent matching performance
is achieved by gliding matching and a
direct matching assembly procedure.
The diodes are delivered on tape in
several matched groups and are also
available unmatched upon request.
The unmatched type, BB158 has the
same specification.
