产品详情介绍
MITEQ(现为 Narda-MITEQ)的 PIN 二极管衰减器分模拟和数字两大类,标准品即可做到 60 dB 以上衰减范围,并支持 0.125 dB 最小步进(8-bit 数字型)。典型特点如下:
- 频率覆盖 DC-18 GHz,可定制到 50 GHz
- 衰减范围 0-60 dB(部分型号 63 dB/80 dB),精度高、单调性好
- 插入损耗低(<2.2 dB 典型)
- 控制方式:模拟电压 0-10 V 或 TTL 并行/串行数字码
- 响应速度快,上升时间可低至 150 ns
- 可做成“相位恒定”版本,适合相控阵、雷达、EW 等要求幅度-相位同时精密的场合
- 封装形式既有带 SMA 连接器的模块,也有可直接焊接的 Drop-in 微带片
