The broader impacts/commercial potential of this Small Business Technology Transfer (STTR) Phase I can be found across the semiconductor industry with a very large first market in wireless communications. Due to their extraordinary properties, more specifically, the linearity of these devices, the technologies can find applications in low noise amplifiers, mixers, and power amplifiers in wireless systems by replacing the transistors used in these parts. Such a wireless market is estimated to be ten(s) billion dollars by 2020 driven by mobile data. The high performance of the devices will also lead to radically change of the current cost-performance paradigm allowing for billions of dollars of savings in base stations for current service levels and likely accelerating the displacement of wireline networks. As the technology matures, it will displace most if not all moderate bandgap materials used in today's technology.This Small Business Technology Transfer (STTR) Phase I project will develop electronic devices for radio frequency (RF) application using carbon nanotubes (CNTs). The demanding for high speed wireless communication requires electronic devices with high linearity. RF devices made of silicon and compound semiconductors, such as gallium arsenide, have to sacrifice power efficiency in order to reach certain linearity specification. CNT is a one dimensional material with diameter in nanometer range. It has far superior properties ranging from mobility to current carrying capability to thermal stability. Calculations show CNT amplifiers will be inherently linear with noise suppressed to the lowest possible quantum limit. These properties allow for electronic devices that will performance better than the existing technologies with high speed, low noise, and most importantly, high linearity. With improved linearity, higher data rate and higher power efficiency (longer battery time of the mobile device) can be achieved. As importantly, the cost for making such devices will be dramatically lower because of the simple method for material synthesis and device fabrication and the material's properties allow for older, cheaper fabrication processes to be retained.

小企业技术转让（STTR）第一阶段的更广泛影响/商业潜力可以在整个半导体行业中找到，无线通信是一个非常大的第一市场。 由于这些器件具有非凡的特性，更具体地说，这些技术可以在无线系统中的低噪声放大器、混频器和功率放大器中找到应用，取代这些器件中使用的晶体管。到2020年，由移动的数据驱动的这种无线市场估计为100亿美元。这些设备的高性能还将从根本上改变当前的性价比模式，从而为当前的服务水平节省数十亿美元的基站费用，并可能加速有线网络的取代。随着这项技术的成熟，它将取代大多数，如果不是所有的中等带隙材料在今天的技术使用。这个小企业技术转让（STTR）第一阶段项目将开发电子设备的射频（RF）应用使用碳纳米管（CNT）。高速无线通信的需求要求电子器件具有高线性度。 由硅和化合物半导体（例如砷化镓）制成的RF装置必须牺牲功率效率以达到一定的线性规格。碳纳米管是一种直径在纳米级的一维材料。它具有从流动性到载流能力再到热稳定性的远为优越的上级性质。 计算表明，碳纳米管放大器本质上是线性的，噪声被抑制到尽可能低的量子极限。这些特性使电子设备的性能优于现有技术，具有高速，低噪声，最重要的是，高线性度。 利用改进的线性度，可以实现更高的数据速率和更高的功率效率（移动终端的更长的电池时间）。 同样重要的是，由于材料合成和器件制造的简单方法，制造这种器件的成本将显著降低，并且材料的性质允许保留较旧的、较便宜的制造工艺。
