In this paper, we propose a low loss 60GHz Radio AiP (Antenna-in-Package) solution for mobile applications. To achieve this low loss AiP, essential passive elements such as transmission lines, transitions, filters and antennas are developed using low temperature co-fired ceramic (LTCC). In order to make packages power efficient, air cavities are inserted; insertion loss is improved by up to 58% for...
A 60GHz transceiver system with low-power CMOS OOK modulator and demodulator is presented in this paper. The 60 GHz modulator is designed in a 90-nm CMOS process by current reuse and consumes 14.4-mW dc power at the ON-state. A data rate of up to 2 Gb/s has been measured. The 60GHz OOK demodulator is designed in a 130nm CMOS process. The demodulator consumes 14.7 mW, and recovers up to 5 Gb/s with...
In this work, the first mu-strip 60 GHz Rotman lens and new compact low loss strip delay line using low temperature co-fired ceramic(LTCC) are proposed. The lens has 3 steering capability for +26deg, -26deg, 0.1deg angle, - 0.86 dB of side lobe level (SLL), and 28deg of half power beam width (HPBW). The Rotman lens is designed in mu-strip structure for integration capability with the system on package...
This paper proposes a low loss and broadband grounded coplanar waveguide (GCPW) to waveguide (WG) transition in a low temperature co-fired ceramic (LTCC) multi-layer structure for 60 GHz applications. The GCPW and WG are fully integrated on the same substrate, and the ground wall of the embedded WG is made up of a staggered via fence. A 3lambda/4 bent short stub is connected between signal line of...
