76 GHZ to 81 GHz LNA Phase Array
The WEA7681L130 consists of phase array element of 4 LNAs and a combiner.
Overview
The WEA7681L130 consists of phase array element of 4 LNAs and a combiner. Each LNA has 3 stages. The WEA7681L130 functions as a MUX. Every LNA stage current is programmable. The chip has a build in FIFO for consecutive LNA sequencing operation. The chip has 3 integrated monitors i) 2.5V chip supply, ii) 1.2V LDO supply and iii) the chip temperature. The LNA gain is controlled by current steering of the last stage together with the LNA bias current on each stage. The chip has been implemented in the 130nm BiCMOS GlobalFoundries process.
