SX1701BRF/IF射頻/中頻RFID的射頻放大器規(guī)格書PDF中文資料

SX1701B屬于RF/IF射頻/中頻RFID的射頻放大器。由Semtech Corporation制造生產(chǎn)的SX1701B射頻放大器在射頻應(yīng)用中，射頻放大器產(chǎn)品可用于信號增益和緩沖。這些產(chǎn)品與通用運算放大器的不同之處在于，它們通常適用于更高的頻率，更傾向于提供不可調(diào)節(jié)的固定增益，并且輸入或輸出阻抗值符合常用傳輸線特性阻抗。

GENERAL DESCRIPTION

The SX1701B is an integrated LNA operating over a wide frequency range from 40 MHz to 2.5 GHz. It is optimized for high OIP2 and OIP3 with minimum current consumption. It also performs a single-ended to differential conversion.

Two independent output channels are available and the gain of each may be adjusted independently.

KEY PRODUCT FEATURES

? Single-ended input / Dual differential outputs

? Independent programmable gain for each channel: 6, 12 and 18 dB

? High Linearity: OIP2 of 57 dBm and OIP3 of 22 dBm

? Noise Figure of 7 dB

? 75 ? Input impedance

? 100 ? differential output impedance

? Current consumption of 130 mA with one channel enabled

? ESD protection (Normal ESD handling procedures should be observed)

? Very small package: MLPQ-16, 4 mm x 4 mm (equivalent to QFN-16, 4 mm x 4 mm)

APPLICATIONS

? Digital Set Top Boxes (Satellite and Terrestrial)

? CATV Distribution Systems

? Active Splitter

? Data Communications Systems

? Active Balun
