SKY12343-364LF中文资料0.01 – 4.0 GHz Seven-Bit Digital Attenuator with Serial and Parallel Drivers数据手册Skyworks规格书

描述 Description

Please note: SKY12343-364LF is being discontinued and is not recommended for new designs.

The SKY12343-364LF is a GaAs broadband seven-bit pHEMTdigital attenuator with a 0.25 dB Least Significant Bit (LSB). ATTL/CMOS-compatible, dual mode serial or parallel programminginterface (SPI) controller is integrated into the device.

The SKY12343-364LF attenuator features low insertion loss,excellent attenuation accuracy, a 31.75 dB attenuation range, andhigh linearity performance. The device is an ideal choice for awide variety of 3G and 4G cellular infrastructure applications.

Attenuation is controlled by an SPI controller. Depending on theSPI sequence applied to the DATA_IN pin, the attenuation statebetween the RF1 and RF2 pins is programmed between a lowinsertion loss state or up to 31.75 dB. The V1 through V7 DCcontrol pins determine the attenuation state if parallel mode isenabled.

特性 Features

• Broadband operation: 0.01 to 4.0 GHz
• Attenuation range: 31.75 dB with 0.25 dB LSB
• TTL/CMOS-compatible serial, parallel, or latched parallel control interface
• Single supply voltage: +3.3 or +5 V
• Small, QFN (32-pin, 5 x 5 mm) Pb-free package (MSL1, 260 °C per JEDEC J-STD-020)

简介

SKY12343-364LF属于RF/IF射频/中频RFID的衰减器。由制造生产的SKY12343-364LF衰减器衰减器旨在降低信号功率，同时尽量减少其对波形的影响。衰减值的范围为 0 dB 至 69 dB，频率范围为 0 至 86 GHz。
