U2791B  
TELEFUNKEN Semiconductors  
1000 MHz Quadrature Demodulator  
Description  
U2791B silicon monolithic integrated circuit is a gain, power down mode and is adjustment free. The IC is  
quadrature 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  
100 – 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 100 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
