原创 还是射频有钱景 Intel投资RF初创公司千万美金

Intel投资7月3日宣布给Mirics半导体投资1000万美金，这家英国背景的公司成立与2004年，主要研发射频芯片，它们推出的MS1001 射频Tuner芯片号称可以让移动设备和PC接收基于全球众多技术标准的服务，因为它的带宽有100KHz到1.9GHz之宽。另外一个优点是它具有比已有方案更小的芯片尺寸和更低的功耗。

Mirics aims to provide the receiver function for TV and radio at the same cost and power level as FM radio alone. All the chip's signal processing is analog, and the chip reconfigures and reconnects its on-chip functional blocks in response to external commands, depending on the band and signal type. This reconfiguration extends to the basic architecture of the receiver function. In some cases, the receiver uses a direct-conversion, zero-IF layout; in others, it uses a conventional heterodyne architecture. The MS1001 has five RF inputs with individual on-chip low-noise amplifiers. It yields quadrature output signals, and you use a three-wire serial digital port to control the device's configuration, which you can change dynamically. As well as providing a single receiver chip for all bands, Mirics asserts that its product is the cheapest and lowest power device available, at $3.50 (10,000). Mirics aims to further reduce the cost to make the device competitive with chips that provide the FM function alone and to exploit mixed-signal capability to add a flexible on-chip digital demodulation capability.

总之就是FM和TV集成，可配置且配置灵活，比如零中频和超外差都支持；有五个RF输入和独立的低噪放；三线控制。未来发展就是增加片内数字解调功能和推出单FM芯片。

虽然展讯成功上市，硅谷数模、凯明、锐迪科和天碁科技也入选第六版全球60家最具潜力半导体初创公司，但是其中只有锐迪科是手机RF公司，看来国内的模拟IC设计还是有很大的发展空间。
