TELEFUNKEN Semiconductors
U2795B
2.5-GHz Double Balanced Mixer
Description
U2795B is a 2.5-GHz mixer for WLAN and RF telecom-
munications equipment, e.g., DECT and PCN, built with
TELEFUNKEN’s advanced bipolar technology. 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.
Features
D Supply voltage range: 2.7 to 5.5 V
D Single-ended output, no balun required
D Single-ended input for RF and LO
D Exellent isolation characteristics
D Power down mode
D IP3 and compression point programmable
D 2.5-GHz operating frequency
D SO-8 package
Benefits
D Reduced system costs due to few external component
(no balun) requirements
D Standard independent product
D 3-V operation reduces the battery count and saves
space
