A-132 GPS Flange 天線


介紹

A-132GPS天線,在底端具有RF保護隔離設備,和一個3英寸的鋁製緣盤,以加強GPS信號之接收。A-132 備有3組信號雜訊濾波器和2階段訊號放大器,這將能提供GPS設備最準確的信號。A-132強大的信號接收,最適合有整合或開發自己GPS產品能力的客戶。A-132 可專門做為多功能的整合應用,如GPS追蹤產品等等。天線為標準的電源輸入,電壓範圍從3V〜6V。如同極星所生產的其它天線一樣,A-132符合RoHS的標準。

特征

A-132 GPS Active 天線s is the only innovating design 天線 with performance, quality and a Power protection circuit built-in to protect the active LNA’s, and most importantly the host GPS receiver down the connector end from the danger of a SHORT circuit external 天線 (Note: GPS receiver front-end can be destroyed or de-graded by an external GPS 天線 in an over-load or short conditions. The A-132 is a low profile GPS active 天線s system for the next generation multi-purpose GPS mobile 天線 products for Telematics, Fleet Management, Navigations and AVL applications. This small print size of the 天線 design does not reflect over-all performance, since the 天線 itself needs no ground plane aid to deliver the L1 band small signal carrier that originates from the 24 orbiting USA satellites located thousands of miles over-head and with the ground reception power sensitivity at over -130dB. The A-132 天線 is also design as a standard power input voltages in range from +3Vdc to +6Vdc with reverse polarity shutdown, over-current sense shutdown and an EMC power line suppression. The most important over-all design concept of the A-132 GPS Active 天線s is the complete protections of the host sensitive GPS receiver made from any manufacturer that it serve and can also be destroy or de-grade using an improper design 天線
