DPF 2/...-125
Duplex Filter for the 160 MHz Band
DESCRIPTION
High power base station duplex filter for the 140 – 175 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.
