SKY12332-470LF中文资料10 MHz - 1.0 GHz Six-Bit Digital Attenuator with Driver (0.5 dB LSB, 31.5 dB Range)数据手册Skyworks规格书

描述 Description

Please note: SKY12332-470LF is being discontinued and is not recommended for new designs.

The SKY12332-470LF is a six-bit digital GaAs attenuator with an onboard, low-noise CMOS driver. This attenuator offers excellent performance from 10 MHz to 1.0 GHz, which makes it ideal for IF and RF level control applications.

The SKY12332-470LF contains an onboard CMOS driver circuit that accepts CMOS logic levels at the six control inputs and produces a negative supply voltage to control the GaAs attenuator.

The device has excellent linearity for compatibility with non-constant envelope signals such as WCDMA and OFDM. The six attenuation bits are binary weighted with an LSB of 0.5 dB and a total nominal attenuation range of 31.5 dB. The device also has excellent attenuation accuracy and is monotonic. The low-noise CMOS driver enables a very low RF noise floor, typically –100 dBm.

The device is provided in a 5 x 5 mm, 32-pin Quad Flat No-Lead (QFN) package.
