U2797B General Description

The IC U2797B is a 1000-MHz quadrature modulator that uses TELEFUNKEN's advanced UHF process. It features a frequency range from 100 MHz up to 1000 MHz, low current consumption, and single-ended RF and LO ports. The I/Q input impedance is about 150 k. Adjustment free application makes the direct converter suitable for all digital radio systems up to 1000 MHz, e.g., GSM, DAMPS, PDC.
