SKY65605-21数据手册RF/IF射频/中频RFID的射频放大器规格书PDF

描述 Description

The SKY65605-21 is a Microwave Monolithic Integrated Circuit(MMIC) front-end low-noise amplifier (LNA) designed for BeiDouSatellite Navigation System/Global Positioning System/GlobalNavigation Satellite System (BDS/GPS/GNSS) receiverapplications. The device provides high linearity, excellent gain, ahigh 1 dB input compression point (IP1dB), and a superior noisefigure (NF).

The SKY65605-21 is optimized to operate from 1.559 to1.606 GHz, which makes it ideal for BDS/GPS/GNSS radioreceiver applications.

The SKY65605-21 is fabricated using advanced SiGe BiCMOStechnology. The LNA uses surface-mount technology (SMT) in theform of a 0.7 x 1.1 mm Quad Flat No-Lead (QFN) package, whichallows for a highly manufacturable and low-cost solution.

特性 Features

• Small signal gain: 19 dB typical
• High in-band IIP3: –5 dBm
• Low noise figure: 0.6 dB typical
• High IP1dB: –14.5 dBm
• Low current consumption: 3.6 mA
• Input/output impedance internally matched to 50 Ω
• Single DC supply: 1.8 to 2.85 V
• Minimal number of external components required
• Ultra-small QFN (6-pin, 0.7 x 1.1 mm) package (MSL1, 260 °C per JEDEC J-STD-020)

应用 Application

• Smartphones
• Remote Keyless Entry

简介

SKY65605-21属于RF/IF射频/中频RFID的射频放大器。由制造生产的SKY65605-21射频放大器在射频应用中，射频放大器产品可用于信号增益和缓冲。这些产品与通用运算放大器的不同之处在于，它们通常适用于更高的频率，更倾向于提供不可调节的固定增益，并且输入或输出阻抗值符合常用传输线特性阻抗。
