The TR2_120_017 integrated frontend transceiver is ideal for operation in the ISM band (122 GHz – 123 GHz), consisting of one transmit and two receive channels, and antennas incorporated within the device package. The transmitter channel features a gain-controlled power amplifier and the two receiver channels each have a gain-controlled low-noise amplifier, a quadrature mixer and poly-phase filter. The on-chip VCO provides a tuning range of more than 6 GHz. The device is housed within a LGA66, 6 × 10 mm² package.
The primary application for TR2_120_017 is short range radar systems with a range of up to about 10 meters. By using dielectric lenses or reflectors, the range can be increased considerably. The TR2_120_017 can be used in FMCW mode as well as in CW mode. Although the chip is intended for use in the ISM band, it is also possible to extend the bandwidth to the full tuning range of typ. 6.5 GHz. Its high operating frequency and high output power enable measurements with improved range accuracy and maximum detection range. The two receiver channels provide a radar structure where angular resolution is increased, and target angle of arrival measurements can be performed.
