The 80GHz millimeter wave radar transmitter chip has undergone formal testing using a spectrograph in a professional electromagnetic dark room.
Test results:
The testing of five chips met the design expectations, indicating that the spectrum response and performance of the chip met the expectations.
The gain of AIP5 has increased by 5dB compared to the PCB antenna index, which is in line with the expected results.
AIP2 and AIP4 are combined versions, which increase the measurement by about 2dB compared to the on board antenna's one transmission and one reception, and also meet the expected results.
Design and performance advantages:
Integrating RF, isolator, and antenna into the chip can help reduce design costs.
The success of the chip has validated the effectiveness of the antenna design within the chip, breaking through the bottleneck of radar hardware design.
This chip is expected to shorten the development cycle of radar ranging and improve research and development efficiencBy using ordinary boards to achieve radar ranging, it is expected to reduce research and development costs.
