1.1Features
Radar front end (RFE) with on-chip antenna
Wide bandwidth of 45 GHz in frequency band of ISM band at 245 GHz
Integrated low phase noise VCO
Receiver with homodyne mixer
Fully ESD protected device
QFN 40 pin package, 5mm x 5mm with 0.4mm pitch, Pb-free, RoHS compliant
IC is available as bare die, in package,on Radar Front End for evaluation with Evalkit Easy r4 and optionally with lensOverview

The radar front end TRAˍ240ˍ091 is an integrated transceiver circuit for 240-GHz operation with on-chip antenna.
It includes a voltage-controlled oscillator, divide-by-8 frequency divider, an SPDT switch, a frequency multiplier-by9 chain, frequency doublers, mixers, a low-noise amplifier, a power amplifier, antenna-coupler and integrated
antenna (see Figure 1). For proper functionality, a lens must be placed on top of the chip. The lens can be provided
by Silicon Radar.
The RF signal from the oscillator is amplified and fed to the frequency multiplier-by-9 chain and, and via a coupler
to the integrated antenna. The RF signal from the oscillator is also directed to the RX path via amplifier andfrequency doubler. The RX signal from the antenna is converted to baseband by a mixer with multiplied LO-signal.
The 13.5-GHz VCO has two analog tuning inputs with different tuning ranges and tuning slopes. Both tuning inputs
have to be used to obtain the wide frequency tuning range of 45 GHz. The analog tuning inputs together with the
integrated frequency divider and external fractional-N PLL can be used for frequency modulated continuous wave(FMCW) radar operation. With fixed oscillator frequency it can be used in continuous wave (CW) mode. Other
modulation schemes are possible as well by utilizing the analog tuning inputs.
The IC is fabricated in SG13G2 SiGe BiCMOS technology of IHP GmbH.

1.2Applications

The main field of application of the 240-GHz transceiver radar front end (RFE) is in short range radar systems which
require high range resolution. 45 GHz of bandwidth theoretically gives a radar range resolution down to 6mm in air,and better than 6 mm for other materials with refractive index higher than one. The range resolution is inversely
proportional to the refractive index of the material.
The maximum range depends on the gain of the lens that is used, and it can reach several meters. By using lenses
with higher gain, the range can be increased.
The RFE can be used in FMCW mode as well as in CW mode.

Suggested application circuit

Power Cycling

It is possible to reduce power consumption by power cycling the radar front end. Rapid power cycling with voltage
rise times between 10 µs and 100 µs is possible. At power-up, it must be ensured that no input signal is driven highbefore the supply voltage is stable. At power-down, all input signals must be pulled low before the supply voltage
is switched off.

6.3

Evaluation Kit

Silicon Radar offers evaluation kits for speeding up radar development. Please review our website and productsheets for more information: https://www.siliconradar.com/evalkits/.
The SiRad Easy® r4 platform supports development for many of Silicon Radar’s integrated IQ transceivers including
radar front end boards for TRAˍ240ˍ091. It serves as reference hardware and provides a design environment
including a graphical user interface for parameter setting. Its functionality and communication protocol are
adaptable to development projects.

6.4

Input / Output Stages

The following figures show the simplified circuits of the input and output stages. It is important that voltages applied
to the input pins should never exceed the related VCC by more than 0.3 V. Otherwise, supply current may be sourced
through upper ESD protection diodes connected at the pin.
