F1358工作于TDD频段42和43，其高线性度和高集成度可降低成本，减小面积和功耗
美国加利福尼亚州圣何塞，2015年7月29日 - IDT公司（IDT®）（NASDAQ：IDTI）今天宣布推出一款全新RF器件，可以帮助TDD蜂窝基站开发人员大幅降低功耗、设计方案成本和电路板面积。F1358集成式数字预失真（DPD）解调器工作频率从3200 MHz到4000 MHz，能够提供业界最高的线性度和集成度，从而可提升蜂窝基站数字预失真发射器线性化路径的性能。
F1358集成有数字步进衰减器（DSA）和单极双掷开关（SP2T），该新产品加入到IDT公司不断增长的RF产品系列，补充了另外两款非常受欢迎的高性能解调器产品：工作在400 MHz 到1200 MHz的F1320，以及工作在1300 MHz到2900 MHz的F1370。IDT所有的DPD解调器都采用了IDT专利的Zero-Distortion™（零失真™）和Glitch-Free™（无干扰™）技术，并且引脚兼容。
F1358解调器改进了发射器相邻信道泄漏比（ACLR）性能，同时不再需要外部中频（IF）放大器、平衡不平衡转换器（baluns）、开关和DSA，从而降低了成本。与传统的解决方案相比，F1358降低功耗超过1瓦，具有非常高的可靠性，在高达105℃工作温度下截点为42 dBm。
IDT公司RF部总经理Chris Stephens介绍说： “与IDT公司之前发布的用于较低频段的F1370和F1320一样，F1358数字预失真解调器可提供性能方面的黄金标准，能够为TDD RF开发工程师提供更高集成度、更低成本、更小面积和更低功耗。F1358是用于3到4 GHz TDD系统线性基站收发台（BTS）发射器理想和灵活的解决方案。”
F1358数字预失真解调器现在可以一个6×6mm 36-VFQFPN封装供货。
