单收电视站近几年有较大的发展,由于低噪声砷化镓场效应放大器发展很快,促使低噪声场效应放大器(LNA)的价格迅速下跌,4 GHzL、N、A 在7年内下跌了10倍(目前单价180美元),再加上电视门限扩展解调器(TED)、天线、卫星通信、卫星广播不断发展,使单收电视站近年的发展突飞猛进,预期还会有更大发展前途。
In recent years, the development of single-receiver TV stations has been greatly improved. As the low-noise GaAs FETs have been developing rapidly, the price of low-noise LNAs has rapidly dropped. As a result, the 4 GHz, N, and A lowers in 7 years (Currently $ 180). Coupled with the continuous expansion of the TED, antenna, satellite communications and satellite broadcasting, the development of single-receiver television stations has progressed by leaps and bounds in recent years. It is expected that there will be further development future.
