60 GHz Millimeterwave Short Data Link

The ADMV9625 is a complete millimeterwave (mmWave) wireless connectivity solution in a small printed circuit assembly (PCA) format. All millimeterwave signals are confined to the printed circuit assembly, simplifying implementation. Wireless transmission is achieved using the integrated circularly polarized omnidirectional patch antenna array, which enables communication in many applications, including rotation. Following the antenna array is an integrated diplexer that provides isolation between the separate transmit and receive paths on the board, which reduces multipath distortion. The receive path integrates all components to demodulate the 63.2625 GHz frequency to baseband signals. The flexible receiver gain control is programmable over a wide range to easily accommodate the required link budget. The receiver baseband outputs are ac-coupled and can provide almost 400 mV of differential output signal level. Likewise, the transmit path integrates all components to modulate input baseband signals to 59.85 GHz. The transmitter has programmable gain control to maintain level transmit power. The transmit baseband inputs are dc-coupled and have a broad common-mode input range. Synthesizers are integrated to maintain excellent frequency stability vs. temperature. The simple amplitude modulation (AM) scheme eliminates the need for external data converters, allowing for bit rates of greater than 1 Gbps. On-board power management is integrated to a single 5 V voltage rail to power the ADMV9625.

Together with the ADMV9615, the ADMV9625 provides a complete full duplexed 60 GHz data link for high speed data transmission in the unlicensed 60 GHz industrial, scientific, and medical (ISM) band.
