摘要

介绍了一种低功耗V波段多用户Gb/s通信接收机。该设备在52GHz到57GHz三个频段工作。该芯片包括一个宽带LNA、一个次谐波混频器、一个中频放大器和一个输出负载为50欧姆的驱动器。采用直接转换结构实现高相邻信道抑制。由于次谐波混频器，接收器需要一个外部的低频本振信号。LNA功耗为32mW，峰值增益为14dB，最小NF为5dB。其3dB测量带宽为37% (52-75GHz)。整个接收机功耗76mW，最大转换增益29dB，在0.3mm2的面积上具有2.5GHz的中频高带宽。

Multiband receiver for Gb/s communication at mm-wave frequencies

A low power receiver at V band for multi users Gb/s communication is reported. The device operates in three bands from 52GHz to 57GHz. The die includes a wide band LNA, a sub harmonic mixer, an IF amplifier and a driver to 50 Ohm output load. The direct conversion architecture was chosen to achieve a high adjacent channel rejection. The receiver requires an external lower frequency LO signal thanks to the sub-harmonic mixer. The LNA consumes 32mW and achieves a peak gain of 14dB and a minimum NF of 5dB. Its 3dB measured bandwidth is 37% (52-75GHz). The whole receiver consumes 76mW and achieves a maximum conversion gain of 29dB with a high IF bandwidth of 2.5GHz in an area of 0.3mm2.
