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.
