PROCOM Duplex filter DPF 2/33-125

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. Specifications Electrical Model DPF 2/22-125 DPF 2/33-125 DPF 2/33-125 Frequency 140 – 175 MHz Max. Input Power 300 W Min.
