• Supply Voltage 5 V 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-W Single-ended LO and RF Port
• LO Frequency from 100 MHz to 1 GHz
• SO16 Package01/03
• 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

Electrostatic sensitive device. Observe precautions for handling.
1000-MHz Quadrature Modulator

U2790B

The U2790B is a 1000-MHz quadrature modulator using 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.
