U2790B

1000-MHz Quadrature Modulator

Description

The U2790B is a 1000-MHz quadrature modulator using direct converter suitable for all digital radio systems up

TEMIC Semiconductors’ advanced UHF process. It to 1000 MHz, e.g., GSM, ADC, JDC.

features a frequency range from 100 MHz up to

1000 MHz, low current consumption, and single-ended Electrostatic sensitive device.

RF and LO ports. Adjustment-free application makes the Observe precautions for handling.

Features

Benefits

Supply voltage 5 V (typical)

No external components required for phase shifting

Very low power consumption: 150 mW (typical) for

–1dBm output level

Adjustment free, hence saves time

Only three external components necesary, this results

in cost and board space saving

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: –10dBm (typical)

50- single-ended LO and RF port

LO frequency from 100 MHz to 1 GHz
