... Electrostatic sensitive device. Observe precautions for handling. Description The U2790B is a 1000-MHz quadrature modulator using Atmel´s advanced UHF pro- 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 ...

... The values used for the measurements are CLO and nF. RFo The U2790B-FP (SO16) has an integrated biasing network which allows AC coupling of the baseband signal at a low count of external components. The bias voltage is 2.5 V± 0.15 V. Figure 19 shows the baseband input circuitry with a resistance of 3.2 kW for each asym- metric input. The internal DC offset between A and A, and B and B is typically < ...
