LESHAN RADIO COMPANY, LTD.
VHF Variable Capacitance
Diode
FEATURES
· Excellent linearity
· Excellent matching to 0.7% DMA
· Very small plastic SMD package
· C28: 2.5 pF; ratio: 16.
· Low series resistance.
APPLICATIONS
· Electronic tuning in VHF television
tuners, band B up to 460 MHz
· VCO.
DESCRIPTION
The BB133T1 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 un-
matched type, BB150 has the same
specification.
