Hi,
We have a RF receiver chip with die and we bording it directly on the PCB. The measurements is OK from the 5V to 2.4V supply. We also packged it with SOP-8 form. But the measuremsts shows that it is OK for the 5V to 3.3V. But below 3.3V, the sensitivity started to decrease and even failed to work under 3V supply. I am wondering why my chip with package have worse permance than the die?
Anyone pls. give me some light on it? I dodn't undesratsnd why the working supply have problem with package?
Thanks in advance
