Standard Gain Horn Antenna
- Select
Standard gain horn antennas are used as calibration devices that measure the gain of other antennas.
These antennas are made up of a combination of a Waveguide to Coax Adapter and Standard Gain Horn with Waveguide Input. It is a kind of simple combination but with great care and attention to create an antenna with accurate and suitable specs.
FT-RF Standard gain horn antenna product series includes waveguide sizes WR28, WR42, WR51, WR62, WR75, WR90, WR112, WR137, WR159, WR187, WR229, WR284 and WR340, WR430, WR510, WR650, WR770, WR975, WR1150, WR1500, WR1800, WR2100, WR2300, with broadband waveguide horn antennas have frequency capabilities ranging from 320Mhz to 40 GHz depending on type and style. with the gain of 10dBi, 15dBi, 20dBi and 25dBi.
Standard Gain Horn Antenna Applications:
- - Antenna measurement
- - Radar Detection System
- - Wireless Communication
- - Spectrum Monitoring

13吋iPad Pro厚度僅5.1公厘 史上最薄蘋果裝置

蘋果7日發表睽違18個月的iPad新品,如外界預期發表兩款iPad Pro,皆內建最新M4晶片且比上一代更輕薄,其中13吋iPad Pro厚度僅5.1公厘,是史上最薄蘋果裝置。蘋果另發表兩款iPad Air、Apple Pencil及魔術鍵盤。
Horn antenna2022年10月蘋果發表第六代iPad Pro至今已過18個月,是iPad史上最長的新品等待期。蘋果不負眾望發表11吋及13吋兩款iPad Pro,並推出3年多來首度全新改版設計,除了將FaceTime視訊鏡頭移至較長側邊之外,也首度讓兩款iPad Pro改用P-OLED(串聯式有機發光二極體)螢幕。更重要的是,新一代iPad Pro運算核心一口氣從上一代內建的M2晶片跳級到M4晶片,超越最新MacBook Pro的M3晶片。
蘋果7日另發表11吋及13吋兩款iPad Air,皆採用M2晶片,運算速度比上一代快50%。11吋售價599美元起,13吋售價799美元起。即日起接受預訂,下周開始出貨。
早在7日發表會開場前,蘋果已向外界預告Apple Pencil將是本次發表會的亮點之一,因為蘋果官網在發表會前夕秀出的蘋果圖像暗藏玄機,只要將游標移至蘋果圖像上,圖像就會被擦除一部分,暗示新一代Apple Pencil主打橡皮擦功能。
雖然2018年蘋果推出的第二代Apple Pencil已內建橡皮擦功能,但使用者必須手指輕觸筆桿兩下才能開啟功能。新一代Apple Pencil讓使用者以更直接的方式切換功能,只要手指緊捏筆桿一下就會獲得觸覺反饋,透過筆桿震動得知橡皮擦功能已開啟。
