We recently launched the HA-02M03G01-NF, which is considered an upgrade version of HA-02M03G-NF with attributing to the persistent research of FT-RF CEO - Mr. Chen and RD team. This becomes one of the largest designs in the line of Double Ridged Antennas, despite the fact that the product weighs only 15kg. 

This product's specifications are listed below. With a frequency range of 200 MHz to 3 GHz, it was tested at 3 different distances: 1M, 3M, and 10M.

日本央行 (Bank of Japan) 周四 (22 日) 維持既定的超寬鬆利率政策和購債計畫不變，合乎市場預期，日元兌美元亞洲盤盤中一度貶破 145，是 1998 年以來首見。

另外考量當前情勢，日本央行也決定，與新冠肺炎 (COVID-19) 相關的金融支援特別公開市場操作在接下來將階段性的停止，改以資金供給來因應廣泛的資金需求。

日本央行經過 9 月 21、22 日兩天的金融政策會議後，全部委員一致同意維持基準利率於 - 0.1%，而 0% 的 10 年期公債殖利率曲線定錨目標也維持不變，為達成殖利率的誘導目標，不會對長期公債買進設定金額上限。

此外，為了實現前述目標，除了明顯預期無人參與的情況之外，日本央行在每個營業日，都將以 0.25% 的固定殖利率買進 10 年期公債。

針對 ETF 及 J-REIT 的資產買進，日本央行分別設下全年約 12 兆日元及全年約 1800 億日元的餘額增幅上限，並視需求實施買進。商業票據及公司債的買進部分，日本央行計劃逐步恢復至疫情前水準，其中商業票據等約 2 兆日元，公司債等約 3 兆日元，都獲得委員一致通過。

於截稿前，在台北時間周四上午 11:05，美元兌日元匯率在 1 美元兌換 144.75 日元前後徘徊，盤中最低曾貶至 145.37 日元，但跌幅很快收斂。日經 225 指數周四早盤暫收在 27047.37 點，較前一個交易日下跌 0.97% 或 265.76 點。

三井住友首席策略師 Daisuke Uno 說，日本周五為國定假日，交易員可能藉機壓低日元。

日元若持續低於 145，下一個觀察重點將是 146.78，這是 1998 年美日聯合干預匯市以前觸及的價位。

Double Ridged Horn Antenna
Sort by:Select
The horn antenna is a broadband passive device, shaped like a pyramid horn, referred to as a TEM antenna, which guides the beam of radio waves at a precise frequency. FT-RF Double Ridged Horn antennas have frequency capabilities ranging from 400MHz to 40GHz depending on type and style. These series are characterized by a huge frequency range and extremely high input powers. With increasing frequency, the gain rises to a maximum of 18 dBi. At higher frequencies, the increased gain compensates for the increasing cable losses.

The advantages of Horn antenna:

- Wide bandwidth: Because the horn antenna has no resonant parts, it can function over a wide range of frequencies.

- Easy waveguide interface: These antennas are very easy to interface to waveguide due to their shape, but they can also be designed with a transition so that a regular coaxial feeder can be used.

- Easy to make, simple design.

The horn is suitable for both transmitting and receiving purposes, especially suitable for EMC and immunity test measurements.
