DPF 4/...-125
Duplex Filters for the 85 MHz Band
DESCRIPTION
High power base station duplex filters for the 66 – 88 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.
