Skyworks SKY73077-459LF

CDMA, GSM, WCDMA1,5 ГГц ~ 2,7 ГГц

Overview

Skyworks SKY73077-459LF 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 1500 to 2700 MHz range. The high linearity, and excellent I/Q phase accuracy and amplitude balance of the SKY73077-459LF make it ideal for use in high performance communication systems. 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.
