Duplex Filter DPF 70/33-125 ความถี่ (400 – 475 MHz)

หมวดหมู่:

Description

  • High power base station duplex filters for the 400 – 475 MHz range.
  • The use of large ø125 mm cavities means a high Q,
    resulting in a very small duplex spacing.
  • The large dimensions also mean a high power rating.
  • High frequency stability on temperature and power.
  • Mounting brackets for 19” mounting included.
  • Please specify the frequencies for Tx and Rx when ordering.
