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.
