0.01 - 48 GHz, SOI 6-Bit Digital Attenuator: QPC0045
Source: Qorvo
The QPC0045 is an ultra-wideband SOI 6-bit digital step attenuator (DSA). It operates over 0.01 to 48 GHz and provides a 31.5 dB attenuation range with a LSB of 0.5 dB. It also achieves a low step error of less than 0.1 dB typically.
The QPC0045 also offers multiple control options, including parallel, SPI, or I2C, C, as well as the ability to control various DSAs simultaneously using either addressing or daisy chaining.
The QPC0045 is housed in a 3.5 x 3.5 mm on a laminate-based package. This, along with the minimal DC power consumption, allows for easy system integration.
