BB179B

UHF variable capacitance diode

Rev. 3 — 5 September 2011

Product data sheet

1. Product profile

1.1 General description

The BB179B is a variable capacitance diode, fabricated in planar technology and

encapsulated in the SOD523 (SC-79) ultra small SMD plastic package. The excellent

matching performance is achieved by gliding matching and a Direct Matching Assembly

(DMA) procedure.

1.2 Features and benefits

 Excellent linearity

 Excellent matching to 2 % DMA

 Ultra small SMD plastic package

 C_d(28V): 2.1 pF; C_d(1V)to C_d(28V)ratio: 9

 Low series resistance.

1.3 Applications

 Electronic tuning in UHF television tuners

 Voltage Controlled Oscillators (VCO).
