简  介:Features Supply Voltage 5V (Typically) Very Low Power Consumption: 150 mW (Typically) for –1 dBm Output Level Very Good Sideband Suppression by Means of Duty Cycle Regeneration of the LO Input Signal Phase Control Loop for Precise 90° Phase Shifting Power-down Mode Low LO Input Level: –10 dBm (Typically) 50- Single-ended LO and RF Port LO Frequency from 100 MHz to 1 GHz SO16 Package Benefits No External Components Required for Phase Shifting Adjustment Free, Hence Saves Manufacturing Time Only Three External Components Necessary, this Results in Cost and Board Space Saving 1000-MHz Quadrature Modulator U2790B Electrostatic sensitive device. Observe precautions for handling. 1. Description The U2790B is a 1000-MHz quadrature modulator using Atmel’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. Adjustment-free application makes the direct converter suitable for all digital radio systems up to 1000 MHz, e.g., GSM, ADC, JDC. Figure 1-1.
