SKY65903-11数据手册RF/IF射频/中频RFID的射频前端（LNA+PA）规格书PDF

描述 Description

Please note: SKY65903-11 is being discontinued and is not recommended for new designs. The suggested replacement is SKY65933-11

The SKY65903-11 is a front-end module (FEM) with an integratedlow-noise amplifier (LNA), and pre- and post-filters designed forGlobal Positioning System/Global Navigation SatelliteSystem/Beidou Navigation Satellite System (GPS/GNSS/BDS)receiver applications. The device provides high linearity, excellentgain, and a low noise figure (NF).

The pre- and post-filters provide low in-band insertion loss andexcellent rejection for the cellular, PCS, and WLAN frequencybands.

The SKY65903-11 uses surface-mount technology (SMT) in theform of a 2.5 x 2.5 mm Multi-Chip Module (MCM) package, whichallows for a highly manufacturable and low-cost solution.

特性 Features

• Small signal gain: 14.2 dB
• In-band IIP3: –7.3 dBm
• Low noise figure: 1.7 dB
• Low current consumption
• Input/output impedance internally matched to 50 Ω
• Single DC supply: 1.8 V
• No external SMT required
• Small, MCM (16-pin, 2.5 x 2.5 mm) package (MSL1, 260 °C per JEDEC J-STD-020)

应用 Application

• Cameras

• Wearables

简介

SKY65903-11属于RF/IF射频/中频RFID的射频前端（LNA+PA）。由制造生产的SKY65903-11射频前端（LNA + PA）本系列中的产品是各种集成电路，其中集成了射频 (RF) 信号链连接到系统天线的部分中常见的一种或多种功能，如低噪声放大器 (LNA) 和可编程放大器 (PA)。任何给定器件所含的实际功能各不相同，相比旨在提供更高应用灵活性的器件，针对相对较窄应用的器件通常集成更大一部分必要的信号链。
