1.1 Overview
The SiRad Simple® Evaluation Kit is an experimental showcase system for Silicon Radar’s highly
integrated 122 GHz IQ transceiver with antennas in package. For more information about the
features of Silicon Radar’s transceiver chips, all data sheets are available on the Silicon Radar
webpage

.
We developed the evaluation kit to demonstrate our millimeter-wave sensors to measure the
distance and velocity using RADAR principles. Both, frequency modulated continuous wave
(FMCW) or continuous wave (CW), principles are applied.
1.2 Features
The SiRad Simple® Evaluation Kit feature set includes:

phase locked loop (PLL) running the integrated low phase noise Push-Push VCO in the
transceiver chip,

frequency lock control to automatically adjust the start and stop frequencies of the
generated FMCW radar frequency ramp,

programmable FMCW parameters,

122 GHz ISM band or 7 GHz high bandwidth FMCW operations,

analog signal conditioning to amplify and filter the I and Q output signals of the transceiver,

Analog-to-Digital-converter to digitize the I and Q receiver signals,

microcontroller to do
◦
PLL setup, ramp configuration, A-D conversion,
◦
signal processing and target recognition for up to 16 targets simultaneously,
◦
transfer to the host system, trigger configurable GP output pins,

web-based graphical user interface to change relevant parameters, plot the FFT of the
baseband channels, display the distance and velocity measurements and the target list,

standard USB or WiFi communication to PC,

DC-DC conversion to provide single supply from USB or an external DC supply.
1.3 Application
The SiRad Simple® Evaluation Kit is supposed to be used for short-term evaluation purposes in
laboratory environments only. All regulations of the according Silicon Radar Evaluation Agreement
may apply.
IMPORTANT:
The radar frontends are able to use a larger bandwidth than what is allowed in the ISM
bands. In most countries, the bandwidth is limited to 1 GHz between 122 GHz and 123 GHz
for production purposes by law. Please check your local regulations. It is up to the customer
to make sure that the frontend is not used in these conditions.
