Features

• 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

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

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.
