60GHz Monolithic LTCC Module for Wireless Communication Systems

A highly integrated RF module, the so-called system-on-package module, which employs a multi-layer structure, is effective in achieving high-speed wireless communication systems that have a transmission rate higher than 1 Gb/s at millimeter-wave frequencies. We present a 12 × 12 × 1.2 mm3 compact monolithic low temperature co-fired ceramic (LTCC) transmitter module for 60-GHz wireless communication systems. The MMIC includes the power amplifier circuit, voltage controlled oscillator, frequency doublers, and the band-pass filter circuit integrated onto the LTCC multi-layer circuit constructed with a high gain antenna. In this paper, we describe the design and characteristics of the LTCC transmitter module with the band-pass filter circuit and the antenna at 60 GHz.
