Skyworks SKY12343-364LF-EVB

衰减器100MHz ~ 4GHzSKY12343-364

Overview

The SKY12343-364LF is a GaAs broadband seven-bit pHEMT digital attenuator with a 0.25 dB Least Significant Bit (LSB). A TTL/CMOS-compatible, dual mode serial or parallel programming interface (SPI) controller is integrated into the device. The SKY12343-364LF attenuator features low insertion loss, excellent attenuation accuracy, a 31.75 dB attenuation range, and high linearity performance. The device is an ideal choice for a wide variety of 3G and 4G cellular infrastructure applications. Attenuation is controlled by an SPI controller. Depending on the SPI sequence applied to the DATA_IN pin, the attenuation state between the RF1 and RF2 pins is programmed between a low insertion loss state or up to 31.75 dB. The V1 through V7 DC control pins determine the attenuation state if parallel mode is enabled.
