The figure below presents a high-level block diagram of the PCB that houses the USB-based sensor
unit:
Figure 3: High-Level Block Diagram – USB-based system
An SPI-based module is similar, excluding the USB-related components. The following components
are embedded in the sensor unit PCB:

Vayyar VYYR7201-B4 system-on-chip (SoC).

46 embedded Tx/Rx linear polarized PCB embedded, wide-band antennas.

A Crystal used as a clocking source for the Cypress MCU.
A TCXO (Temperature Compensated Crystal Oscillator) used as a clocking source for the
VYYR7201-B4 SoC.

Power supply system supporting 3.3V, 2.5V, 1.27V and 1.2V DC/DC converters.

For USB-based models - a digital interface that communicates with a host PC via a USB-2.0
connection. The interface is implemented using on-board Cypress micro-controller unit
(MCU).

For SPI-based models – the interface is communicating directly with VYYR7201- B4 SoC.
