Description
The SKY12325-350 is a 3-bit digital attenuator in a low cost QFN-16, 3 x 3 mm package. The attenuation bits are binary weighted, with the least significant bit (LSB) 1 dB. States are selected by 3 positive-voltage control inputs. DC blocking capacitors are required at each RF port. Both RF ports are absorptive.
