NEW RELEASE BY RM ITALY: With 4 x MACOM MRF-455<\/strong><\/p>\n

MLA300V: The NEW RM MLA300 ‘black line’ amplifier is replacing the popular HLA300V series. It is a 13.6 VDC HF broadband linear amplifier suitable for use in the range from 1.8 to 30 MHz with a maximum output of 300W, (Av. power), requiring a maxi-mum input drive of 15W, it has been designed to be used with transceivers with 10W outputs but can be used equally well with any transceiver capable of producing 1 to 15W output. It uses 4 RF power transistors in two parallel push pull circuits biased in class AB. There are 6-Low Pass Filters with cut-off frequencies of 3, 4, 5, 8, 15, 22 and 31 MHz that greatly reduce unwanted harmonic output to acceptable levels that may be selected manually or automatically. It features a microprocessor that controls all of the functions of the amplifier and its protection circuits. Protection is provided for excessive input power, excessive output power, excessive load VSWR, out of band operation and excessive temperature. The amplifier may be used either in a mobile \/ portable or fixed station installation.<\/p>\n

In operation, the MLA300 shows its class: the front display provides all important information – output power, VSWR, active filter – and with a maximum VSWR of 2.5:1 it remains calm even with not perfectly tuned antennas.
\nConclusion: The MLA300 is a real workhorse for the radio operator, combining power, flexibility and safety in a compact package. Whether you are hunting DX, contesting or just ragchewing \u2013 with this amplifier you get the most out of your 10-Watts and stay relaxed. RM Italy delivers a product that not only impresses technically, but also makes a radio amateur’s everyday life easier. Watt for watt a win!<\/p>\n
