TRHJ-2060 is a beamforming phased array silicabased (CMOS) chip featuring 4-channel interfrequency receiving and transmitting. Signals are processed through the transmitting and receiving channels respectively at the opening ports, with the receiving operating frequency ranging from 10.7GHz to 12.7GHz and the transmitting operating frequency

ranging from 13.7GHz to 14.5GHz. In receiving mode, input signals are input from RF_RX of the opening port and output from the common port RF_COM through 4 synthesizers. In transmitting mode, input signals are input by RF_IO of the common port and output by 4 RF_TX ports through 4 power dividers. The chip provides 6-bit phase (adjustment range: 360°, step: 5.625°) and 6-bit amplitude adjustment (adjustment range: 31dB, step:

0.5dB). 

A simple four-line serial port (SPI) is adopted for the TRHJ-2060 chip to control the on-chip register. In addition, the four address pins allow the SPI to control up to 16 chips on the same serial line. A specialized LOAD pin can also provide the synchronization of all core chips in the same array. WLCSP capsulation is adopted for TRHJ-2060. The working environment temperature range is −55℃ to+85℃
