Description
The silicon monolithic integrated circuit U2794B is a quadrature demodulator manu-
factured using Atmelâs advanced UHF technology. This demodulator features a
frequency range from 70 MHz to 1000 MHz, low current consumption, selectable gain,
power-down mode and adjustment-free handling. The IC is suitable for direct conver-
sion and image rejection applications in digital radio systems up to 1 GHz such as
cellular radios, cordless telephones, cable TV and satellite TV systems.
