SMV1272-079LF数据手册分立半导体产品的二极管-可变电容（变容器可变电抗器）规格书PDF

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.

特性 Features

• Cross to Renesas HVC350B
• Low-series resistance
• High-capacitance ratio
• Ultrasmall SC-79 package (MSL1, 260 °C per JEDEC J-STD-020)

简介

SMV1272-079LF属于分立半导体产品的二极管-可变电容（变容器可变电抗器）。由制造生产的SMV1272-079LF二极管 - 可变电容（变容器，可变电抗器）可变电容二极管可按照电子可变电容器用途进行生产和分类，并且广泛用于调谐和频率合成应用。虽然大多数二极管的结电容都随着所施加的反向偏压增加而减小，并且能够用作可变电容二极管，但专门作为此类器件销售的产品在生产和分类时特别考虑了这种用途。
