Linear Power Amplifier MKU PA 3440 A

Thisnewpower amplifier using LD-MOSFET technology provides high linearityandhigh efficiency (up to 31 %). Since the amplifier is thermallyverystable and highly linear, it can be used for all operatingmodes.Typical applications are DAB / COFDM / QPSK / DATV /DVB-S / DVB-T.

Features

High voltage and reverse polarity protection

Built-in directional coupler with detector for monitoring the output power - MON -

Milled aluminium case
