Standard Frequency Range YIG Tuned Band-pass Filter
 |
|---|
■ Characteristics
Wide frequency range; Excellent tuning linearity; High out of band rejection; Wide operating temperature range; Digital or analog continious tuning control; Universal SMA input and output interface;
■ Application
Applied in microwave measuring instruments, broad band radar receivers and EW systems;
■ Description
Standard frequency band YIG-tuned bandpass filters cover frequency ranges of 0.5~1 GHz, 1~2 GHz, 2~4GHz, 4~8 GHz, 8~12 GHz, 12~18 GHZ, 18~26 GHz, and 26.5~ 40GHz, providing selective pass of desired microwave signals with electrical tuning. All the YIG-Tuned filters can be offered both independently and combining with special analog or digital drivers.
