描述 Description

The SMV1272-079LF 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 SMV1272-079LF include low-noise andwideband UHF and VHF VCOs for GSM, PCS, CDMA, and analogphones. Table 1 describes the packaging and marking of theSMV1272-079LF varactor.

簡介

SMV1272-079LF屬于分立半導(dǎo)體產(chǎn)品的二極管-可變電容（變?nèi)萜骺勺冸娍蛊鳎?。由制造生產(chǎn)的SMV1272-079LF二極管 - 可變電容（變?nèi)萜?，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(jìn)行生產(chǎn)和分類，并且廣泛用于調(diào)諧和頻率合成應(yīng)用。雖然大多數(shù)二極管的結(jié)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(chǎn)品在生產(chǎn)和分類時(shí)特別考慮了這種用途。
