DAPU RF Passive Devices
1. SMD Circulator / Isolator
The main function of the circulator is to ensure positive lossless passage of signals, as well as high isolation blocking of reflected signals. An isolator is formed by adding a high-power load or attenuator to the third port of the circulator.
Key Features
This series features low loss, low intermodulation, high harmonic suppression, and good impedance-matching consistency.
Applications
Mobile communication, microwave communication, etc.
Type | Freq. range | Dimension | Forward | Return | Insertion | Isolation | IMD |
DPxxxxC | 100 ~ 10000 | ?7~38.1*38.1 | 20~200 | -20 Max | -0.15 ~ -0.35 | -20 Max. | -60 Max. |
DPxxxxS | 100 ~ 10000 | ?7~38.1*38.1 | 20~200 | -20 Max | -0.15 ~ -0.35 | -20 Max. | -60 Max. |
