GENERAL DESCRIPTION

The ADMV9621 is a complete millimeterwave (mmWave) wireless

connectivity solution in a small printed circuit assembly (PCA)

format. All millimeterwave signals are confined to the printed cir-

cuit assembly, simplifying implementation. Wireless transmission

is achieved using the integrated circularly polarized (CP) omnidirec-

tional 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 demodu-

late the 63.0 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 compo-

nents to modulate input baseband signals to 58.0125 GHz. The

transmitter has programmable gain control to maintain level trans-

mit 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 ADMV9621.

Together with the ADMV9611, the ADMV9621 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.
