RM Italy BLA600 Solid State Amplifier

RM ITALY BLA600 Solid State Amplifiers are wideband, compact, automatic linear amplifiers for 160 through 6 meters; 1.8 to 54 MHz. Low input drive requirements (20 to 25W on 80-10 meters, 30-40W for 500W on 160m and 6m) make these amplifiers THE perfect transceiver companion!

RM ITALY BLA600 amplifiers are fully automatic 500W solid-state linear amplifiers suitable for seamless integration with all modern transceivers. They utilize the rugged NXP / Freescale MRF6VP5600H 50V power MOSFET for high power and high reliability.

These amplifiers are capable of all modern modulation modes. BLA600 amplifiers are fully automatic, featuring instant RF frequency-reading for band changes and fast, reliable and silent PIN diode TX-RX switching, making them ideal for CW QSK operation.

These amps have three (3) antenna outputs that are easily configurable on a per-band basis as per the user's requirements. Their RF deck is supplied by a heavy-duty linear power supply, with 240 volt AC input (115-120 or 230 Vac capable) and utilizes an efficient active bridge rectifier with very high-grade filter capacitors to provide the PA devices with a very low noise and robust 50V DC.

The amplifier's RF deck has a large heat spreader and copper heat sink which provides a very efficient cooling system. There are separate fans for the RF deck and LPF board / power supply for high duty cycle operation. Internally, all modules are mounted in a very robust and well-screened enclosure.

BLA600 amplifiers feature Dual MCU control and an extensive array of protection circuits that look after the amplifier with rapid reaction time. VSWR, I/P Power, I/P Frequency, Three Temperature sensors; Transistor / Heat sink and PSU, Drain voltage / Drain current and HV PIN supply are all continuously monitored.

If your HF transceiver can be set for 20 to 40 watts output, then you will be sending 500 watts to the antenna on ALL bands 160 through 6 meters using this amplifier. The real beauty is that it all happens fully automatically! There is no tuning and no band switching! Give your signal a nice boost.
