A 10-Gb/s optical receiver array with low interchannel crosstalk is realized by exploiting an InGaP-GaAs heterojunction bipolar transistor technology in a three-dimensional multilayer low-temperature cofiring ceramics (LTCC) module. Neutralization feedback circuit with LTCC embedded bus structure is proposed to suppress significant high-frequency crosstalk from on-chip bus and intermetallic capacitance. This module demonstrates 5 dB better suppressed-coupling than a conventional on-chip bus module with 0.8-dB power penalty.
