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