Qorvo’s QPC0045 is an ultra-wide band SOI 6-bit digital step attenuator (DSA). It operates over 0.01 to 48 GHz and provides 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 typical.
The QPC0045 also offers multiple control options including parallel, SPI, or I2C as well as the ability to control multiple DSAs simultaneously using either addressing or daisy chaining.
The QPC0045 is housed in a 3.5 x 3.5 mm on laminate-based package. This, along with the minimal DC power consumption, allows for easy system integration.
