United Monolithic Semiconductors has utilized its expertise on the design, manufacture and marketing of leading edge RF and millimeter wave components and solutions to develop the newly introduced CHC2442-QPG, a state-of-the-art, fully integrated 24 GHz transceiver solution for industrial sensor and automotive radar applications. Designed specifically to address sensor applications in the 24 GHz ISM band, the transceiver provides a fully integrated front-end. It offers a high level of flexibility, which can make it the basis for a wide range of industrial sensors, from short range car applications to robotic and peripheral security systems.

LEADING EDGE PERFORMANCE

The CHC2442-QPG includes a signal generation Tx and a dual reception Rx in a single component. This solution is claimed to offer leading edge performance due to a low phase noise voltage controlled oscillator (VCO), a high transmit power level, dual Rx with very low noise figures, all combined with a high level of isolation between Tx and Rx channels. The versatile transceiver also includes power and temperature monitors and a programmable pre-scaler.

The CHC2442-QPG is fully compatible with standard digital interfaces through a serial interface (SPI) with data read and write capabilities. It is available in a surface-mount 28L-QFN4X5 SMD plastic package, is qualified to AEC-Q100 and is also available in high production volumes.

INTEGRATION

A high level of integration and state-of-the-art performance make the CHC2442-QPG a more than suitable solution for industrial sensor and automotive applications. Operating in the -40° to +125°C temperature range,  features include maximum Tx power of >13 dBm with a Tx power control range of 12 dB, Rx gain of 37 dB and an Rx gain control range of 24 dB.
