... Electrostatic sensitive device. Observe precautions for handling. 1. Description The U2790B is a 1000-MHz quadrature modulator using Atmel cess. It features a frequency range from 100 MHz up to 1000 MHz, low current consumption, and single-ended RF and LO ports. Adjustment-free application makes the direct converter suitable for all digital radio systems up to 1000 MHz, e.g., GSM, ADC, JDC ...
