SKY73078-459LF: 500-1500 MHz Quadrature Modulator

Applications

Description

Skyworks SKY73078-459LF is an integrated quadrature

modulator for the upconversion of complex modulated

baseband/IF signals directly up to RF. The device is designed for

use in the 500 to 1500 MHz range. The high linearity, and

excellent I/Q phase accuracy and amplitude balance of the

SKY73078-459LF make it ideal for use in high performance

communication systems.

• Cellular base station systems: GSM/EDGE, CDMA2000,

W-CDMA, TD-SCDMA, LTE

• WiMAX/broadband wireless access systems

• Satellite modems

Features

The modulator accepts two differential baseband inputs and a

single-ended Local Oscillator (LO), and generates a single-ended

RF output. The baseband input buffers accept an input common-

mode voltage of 0.5 V and have a 0.1 dB bandwidth of >65 MHz.

The LO input is broadband matched on-chip to 50 Ω, which

enables a direct connection to a 50 Ω LO source. The RF output is

high impedance, designed for a direct connection to a 50 Ω load.

• RF frequency operation range: 500 to 1500 MHz

• Modulation bandwidth > 65 MHz (0.1 dB), 210 MHz (1 dB)

• Side-band suppression better than –45 dBc

• Carrier feedthrough of –40 dBm

• Noise floor of –158 dBm/Hz
