BB178 - NXP

BB178 VHF variable capacitance diode

The BB178 is a planar technology variable capacitance diode, in a SOD523 (SC-79) ultra small 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 plastic SMD package  Cd(28V): 2.6 pF; C.
