GENERAL DESCRIPTION

The ADMV9623 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 dc-coupled and can provide over 500 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 100 Mbps. On-board

power management is integrated to a single 5 V voltage rail to

power the ADMV9623.
