amplifier mixer的意思|示意

A sealed coaxial matched load at hot or cold condition used in the measurement of low-noise FET amplifier and millimeter wave mixer is described.

本文介绍了一种密封式匹配负载，以及将它置于冷、热态作为一种噪声源在低噪声fet放大器及毫米波混频器测试中的应用。

Based on a direct-conversion architecture, the receiver integrates LNA, I/Q mixer, DC-offset removal filter, baseband amplifier and channel-select filters on a single chip.

基于直接下变频的系统架构，接收机集成了低噪声放大器、I/Q下变频器、去直流偏移滤波器、基带放大器和信道选择滤波器。

What the senior engineer knew was the connection between two sound components — such as receiver, mixer, amplifier, and speakers — went beyond two copper wires and some insulation.

这位资深工程师所知道的就是两个音响部件之间的连接，两段铜线和一些绝缘介质之间的接收器、混音器、放大器和扬声器。

This paper investigates various combined frequency interference in integrated and double-converted transceivers, and points out that the reason is the non-linearity of frequency mixer and amplifier.

研究了一体化二次变频收发信机中各种组合频率干扰的产生原因：主要是由于混频器和放大器的非线性。
