1.5.2. RF specification
RF board consists of single-chip FMCW transceiver capable of operation in the 77- to 81-GHz band.
It is an ideal solution for low power, self-monitored, ultra-accurate radar systems. It consists of 3TX,
4RX system with built-in PLL and ADC converters.
The RF subsystem includes synthesizer, PA, LNA, mixer, IF, and ADC. This subsystem also
includes the crystal oscillator and temperature sensors. The three transmit channels can be operated
simultaneously for transmit beamforming purpose as required; whereas the four receive channels
can all be operated simultaneously.
The transmit subsystem consists of three parallel transmit chains, each with independent phase and
amplitude control. A maximum of two transmit chains can be operational at the same time, however
all three chains can be operated together in a time-multiplexed fashion. Each transmit chain can
deliver a maximum of 13 dBm at the antenna port on the PCB.
The receive subsystem consists of four parallel channels. A single receive channel consists of an
LNA, mixer, IF filtering, ADC conversion and decimation. All four receive channels can be
operational at the same time.
ScanBrick® W support continuous acquisition mode with frequency modulation (FMCW modulation
type).
1.5.3. Applications
ScanBrick® W radar is a Tank Level Probing Radar (TLPR) system.
