BB149
UHF variable capacitance diode
Philips Semiconductors Product specification
UHF variable capacitance diode BB149
FEATURES Excellent linearity Excellent matching to 1% DMA Very small plastic SMD package C28: 2.1 pF; ratio 9 Low series resistance.
APPLICATIONS Electronic tuning in UHF television
tuners VCO.
DESCRIPTIONThe BB149 is a 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 unmatched type, BB159 has the
same specification.
LIMITING VALUESIn accordance with the Absolute Maximum Rating System (IEC 134).
ELECTRICAL CHARACTERISTICS =25 °C unless otherwise specified.
Note VR is the value at which Cd=9 pF.
