U2796B Datasheet, PDF (1/11 Pages) TEMIC Semiconductors – 2-GHz Single Balanced Mixer

2-GHz Single Balanced Mixer
U2796B
Description
The U2796B-FP is a 2-GHz down conversion mixer for
telecommunication systems, e.g. cellular radio, CT1,
CT2, DECT, PCN, using TEMIC Semiconductors
advanced bipolar technology. The U2796B is well suited
for the receiver portion of the RF circuit. Single balanced
structure has been chosen for the best noise performance
and low current consumption. The IIP3 is programmable.
