Description
The U2795B is a 2.5-GHz mixer for WLAN and RF telecommunications equipment,
e.g., DECT and PCN. The IC is manufactured using Atmel's advanced bipolar technol-
ogy. A double-balanced approach was chosen to assure good isolation characteristics
and a minimum of spurious products. The input and output are single-ended, and their
characteristics are programmable. No output transformer or balun is required.
