描述 Description

The SMV1276-079LF is a silicon hyperabrupt junction varactordiode specifically designed for battery operation. The specifiedhigh-capacitance ratio and low-series resistance make thisvaractor appropriate for low phase-noise Voltage-ControlledOscillators (VCOs) used at frequencies in wireless systems up toand above 2.5 GHz.

Applications for the SMV1276-079LF include low-noise andwideband UHF and VHF VCOs for GSM, PCS, CDMA, and analogphones. Table 1 describes the packaging and marking of theSMV1276-079LF varactor.

? Low-series resistance
? High-capacitance ratio
? Ultrasmall SC-79 package (MSL1, 260 °C per JEDEC J-STD-020)

簡介

SMV1276-079LF屬于分立半導體產品的二極管-可變電容（變容器可變電抗器）。由制造生產的SMV1276-079LF二極管 - 可變電容（變容器，可變電抗器）可變電容二極管可按照電子可變電容器用途進行生產和分類，并且廣泛用于調諧和頻率合成應用。雖然大多數二極管的結電容都隨著所施加的反向偏壓增加而減小，并且能夠用作可變電容二極管，但專門作為此類器件銷售的產品在生產和分類時特別考慮了這種用途。
