A 60 GHz LTCC antenna in package with low power CMOS radio

A 60 GHz LTCC Antenna in Package with low power CMOS Radio solution for high data-rate and short-range wireless mobile communication are presented in this paper. For low power consumption, a new type of OOK system is proposed. The 60 GHz OOK transmitter and receiver are designed in 90 nm CMOS process. The transmitter with an OOK modulator and a VCO added an output buffer consumes 27.32 mW power and is able to modulate over 2 Gbps. The receiver with a LNA, a demodulator and a baseband amplifier consumes 12.92 mW and has ability to recover up to 5 Gbps. The OOK system is integrated with low loss compact LTCC AiP. The low loss AiP techniques mainly consist of inter-connection and antenna design methods. The direct wire bonding inter-connection with matched elements has under 1 dB insertion loss. The 60 GHz micro-strip patch antenna has over 90 percent efficiency with LTCC substrate. In the end, high data rate video demonstration using the low power wireless system are presented.
