SKY65723-81中文资料Low-Noise Amplifier Front-End Module with GPS/GNSS/BDS Pre-Filter数据手册Skyworks规格书

描述 Description

The SKY65723-81 is a front-end module (FEM) with an integratedlow-noise amplifier (LNA) and pre-filter designed for GlobalPositioning System/Global Navigation Satellite System/BeidouNavigation Satellite System (GPS/GNSS/BDS) receiverapplications. The device provides high linearity, excellent gain, ahigh 1 dB input compression point (IP1dB), and a superior noisefigure (NF).

The pre-filter provides the low in-band insertion loss andintegrated notch filtering for excellent rejections of the cellular,PCS, and WLAN frequency bands. The SKY65723-81 usessurface-mount technology (SMT) in the form of a 1.7 x 2.3 mmMulti-Chip Module (MCM) package, which allows for a highlymanufacturable and low-cost solution.

特性 Features

• Small signal gain: 16.5 dB typical
• Low noise figure: 1.5 dB typical
• Excellent out-of-band rejection
• Low current consumption
• Input/output impedance internally matched to 50 Ω
• Single DC supply: 1.62 to 3.6 V
• Minimal number of external components required
• Small MCM (6-pin, 1.7 x 2.3 mm) package (MSL3, 260 °C per JEDEC J-STD-020)

应用 Application

• Smartphones

简介

SKY65723-81属于RF/IF射频/中频RFID的射频放大器。由制造生产的SKY65723-81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。
