The SKY12347-362LF is a GaAs pHEMT six-bit broadband digital
attenuator with a 0.5 dB Least Significant Bit (LSB). A Transistor-to-Transistor Logic (TTL)/CMOS-compatible, dual-mode serial or
parallel interface controller is integrated into the device.
The attenuator features low insertion loss, excellent attenuation
accuracy, a 31.5 dB attenuation range, and high linearity
performance. The SKY12347-362LF is an ideal choice for a wide
variety of cellular 3G and 4G infrastructure applications.
Attenuation is controlled by a Serial Peripheral Interface (SPI).
Depending on the SPI sequence applied to the SDI pin, the
attenuation state between the RF1 and RF2 pins can vary
between a low insertion loss state or up to 31.5 dB. The D0
through D5 DC control pins determine the attenuation state if
parallel mode is enabled.
The device is provided in a 4 x 4 mm, 24-pin Quad Flat No-Lead
(QFN) package.
