An AII-GaAs Dual-Gate FET UHF Channel Selector

全砷化镓双栅场效应管的UHF频道选择器

This paper goes into the application of the GaAs Dual-Gate FET to the high frequency tuning-amplification and frequency conversion in a TV UHF channel selector and gives some experimental results.

本文讨论了砷化镓双栅场效应管在电视接收机UHF频道选择器中作高频调谐放大和变频应用时的一些考虑，并给出有关的实验结果。

We'll look closely at the respective functions of the Channel class and the Selector class, and at how the two work together to create a nonblocking I/ O implementation.

我们将仔细考察Channel类和Selector类的各个功能，以及这两个类如何协同工作，创建非阻塞I/O实现。

Like channel selector, band selector also is a kind of RF filters.

和选频类似，选带功能实质上也是一种射频滤波器。
