A 6-30 GHz Compact 3-bit Digital Attenuator MMIC using InP/InGaAs PIN Diodes
A broadband (6-30 GHz) 3-bit digital attenuator MMIC using InP/InGaAs PIN Diodes has been proposed and fabricated. The proposed digital attenuator is composed of Pi- resistive networks for non-reflective step attenuation and fabricated by using a benzocyclobutene(BCB)-based multi-layer MMIC technology. By using the InP/InGaAs PIN diodes having a high cutoff frequency for digital switching, the proposed digital attenuator has shown the low insertion loss and excellent return loss characteristics. The 3-bit digital attenuator has a 3 dB attenuation step and a 21 dB attenuation range. The minimum insertion loss is 4 dB and the input/output return loss is greater than 10 dB over all attenuation states and frequencies. The chip size is 1.47times0.99 mm2.
