1000 MHz Quadrature Demodulator
Description
U2794B silicon monolithic integrated circuit is a quadra-
ture
demodulator
that
TELEFUNKEN’s advanced UHF technology. This
demodulator
features
a
70 – 1000 MHz, low current consumption, selectable
is
manufactured
using
frequency
range
from
gain, power down mode and is adjustment free. The IC is
suitable for direct conversion and image rejection
applications in digital radio systems up to 1 GHz such as
cellular radio, cordless telephone, cable TV and satellite
TV systems.
Features
Supply voltage 5 V (typ.)
Very low power consumption 125 mW (typ.)
Very good image rejection by means of phase control
loop for precise 90
°
phase shifting
Duty cycle regeneration for single ended LO input
signal
Low LO input level –10 dBm (typ.)
LO – frequency from 70 MHz to 1 GHz
Power down mode
25 dB gain control
Very low I/Q output dc offset voltage typ. < 5 mV
