RM MLA-100V 1.8-54MHz (100W) Linear Amplifier with Fan Ideal for QRP Radios
The RM MLA-100V is a compact and efficient 12V linear amplifier designed for amateur radio operators looking to boost the performance of their QRP transceivers. Perfectly matched to radios with a transmit power of 5W, it delivers up to 100W output across 160-10m bands and 80W output on 6m with an 8W drive. With its automatic 7-band low-pass filter system (manual selection also possible), PIN diode RTX switching for seamless operation (including QSK), and comprehensive safety protections, the MLA-100V is both powerful and reliable. The V-version includes a built-in 80mm cooling fan, ensuring safe operation even under heavy use. Wide Frequency Coverage: 1.8-30 MHz (HF) & 50-54 MHz (6m). Output Power: 100W max on HF, 80W on 6m. Drive Power: 1-10W (5W ideal for HF / 8W for 6m). Filters: 7 Low Pass Filters - automatic or manual selection.
Switching: PIN diode RTX switching (supports QSK). Amplifier Transistors: 2 × Mitsubishi RD100HHF1.
Supply Voltage: 13V DC ±1V, up to 25A. Bypass Power (amplifier off): up to 50W. Input VSWR: 1.1-1.8:1.
Output VSWR: max 2.5:1. Better than -50 dBc (1.8-30 MHz). Better than -60 dBc (50-54 MHz). Boosts QRP radios to full 100W output. Compact and lightweight - ideal for portable, mobile, or shack use. Automatic filtering and QSK support for smooth operation. Built-in protections safeguard both amplifier and transceiver.
