Features

PA-10/AIR is linear AM amplifier designed for air-band applications.
It is primarily intended to enhance the range of hand-held transceivers by boosting transmitter power and increasing receiver gain if required.

In the world of aviation, equipment reliability is paramount and PA-10/AIR addresses this need in following ways:

  • AM modulation indicator blinks as user talks, confirming that voice message is transmitted on air. This function immediately points out defective microphone issue.
  • 當放大器無法提供預期的射頻功率時,監控微處理器會識別出這種情況,並立即切換到旁路模式,將收發器直接連接到天線。不會出現透過「燒毀」放大器「傳輸」的情況。
  • 偵測到天線有缺陷或調諧不當的問題並發出訊號。放大器保持旁路模式以保護自身。
  • 由收發器故障或誤用引起的輸入功率過高會導致警報並轉換到旁路模式。
  • 直流電源電壓超出可接受範圍會導致警報,放大器返回旁路模式。
  • 放大器溫度過高引起警報並返回旁路模式

 

所有警示指示燈 (LED) 均為紅色。任何紅色的東西都會亮起——有問題。此方案使用戶不必過多關注信令。

PA-10/AIR 具有自動增益控制功能,由數位步進衰減器實現。它使放大器增益適應收發器不同的載波功率,始終為 AM 調製留有適當的餘裕。不會發生調製削波。

對於接收路徑 – 可以使用低雜訊前置放大器。它還具有輸入帶通濾波器,消除了附近 CB 站引起的交叉調製的危險。
