OM-Power OM-1002+ / OM-2002+ VHF Amplifiers New

OM-Power OM-1002+

OM-Power does not only manufacture very powerful amplifiers for shortwave, but for VHF (2m) as well. The amps OM-1002+ and OM-2002+ offer 800 and respectively 1600W PEP in SSB, which is more than enough for EME and contest operations. The amplifiers are equipped with Freescale N-channel power MOSFET transistors for a worry-free continous operation. With round-about 10kg both power amps are still useasble for portable or expedition purposes. All settings are done via an easy to use colour touch display, which also shows the most important informations.

The devices are equipped with a high-quality swithcing power supply, which provides 50V to the finals. For remote control bith amps are equipped with an Ethernet connection. A Windows software provided for free from the manufacturer allows the control and setting of the most important operating parameters.

LA-250/LA-250V: Amplifiers for 2m (VHF)

LA-250

The LA-250 is a 200 W 140-150MHz amplifier, at 1 to 20 W input (13.6V 30A). It uses 4 Mitsubishi RD70 Mosfets mounted on a copper heat spreader (200x60x3mm). It is available in two versions one with and one without top mounted fans. There is an external PTT input but it can be used also without due to the built-in HF-VOX.

The front panel features an LC Display which shows input power, output power, heat sink temp and output VSWR. There is the ability to change the intensity of the backlight. The CPU keeps an eye on input power, temperature and VSWR and will if necessary disable the amplifier from transmitting if there is fault. Any errors will also be recorded and will be available for later recall for diagnostic purposes by either the manufacturer or his distributors. Weight is approximately 4kg.

Dimensions are approximately 240x420x70 mm for the non fan version and an extra 10 mm of height, 80mm, for the fan version. The LA-250/LA-250V has a large DC connector, a suitable plug is included. You will need a large gauge DC cable additionally (at least 2.5mm² or more).

Blueline ECO750-2M: Efficiency-optimized power amplifier by SSB

ECO750-2M

The Blueline ECO750 by SSB-Electronic is the only power amplifier in amateur radio sector which is based on the Doherty principle and thus offers higher efficiency by more than 20% (SSB mode) than a traditional linear amplifier.

Latest generation components and a highly efficient circuit design result in lower power losses and considerably reduced heat losses.

In addition to the efficiency of the power amplifier itself, much attention was spent on ease of operation and automation of protective functions. An internal sequencer and remote power supply for the antenna pre-amp are of course available.

This amp comes almost without any traditional mechanical operation elements. The high-contrast and bright touch-sensitive display offers a flexible display of operation parameters and its settings, like:

  • Input and Output power
  • Reflected Power
  • Voltage
  • Current

Values of critical functions like excessive input power, over- and under voltage and temperature are continuously measured and displayed. A station clock is also included.

Because of the compact and robust design and the use of selected and very efficient LDMOS semiconductors, this amplifier is extremely suitable for mobile and stationary long-term operation.

Operation is possible at temperatures from 0 °C to 40°C. The highly efficiency-optimized design realy shows off in the field or in a contest situation. Use your resources economically and meaningfully! The high efficiency results in little heat losses, which makes a compact design and low weight possible. This makes the Blueline ECO750 a very reliable companion on your DX Expedition.

The Blueline ECO750 operates with 48V supply voltage. The lack of an integrated power supply is intentional, since there are already suitable supplies in many places. Of course a suitable power supply is available on request.

The benefits of the Blueline ECO750-2m amplifier at a glance:

  • robust, solid workmanship
  • excellent linearity
  • compact design
  • low weight
  • high overall efficiency
  • protection circuits against mismatch, clipping and excessive heat
  • especially suited for digital modes (WSJT)
  • built-in electronic sequence control with remote powering of external preaamplifiers
  • additional time delayed PTT for transceiver
  • remote control

Other features:

  • Microprocessor controlled power amplifier
  • variable PTT control
  • Control by active TFT touch display
  • Display on the TFT touchscreen: Output or input and output power, SWR, temperature, voltage at the DC input, status of the remote supply of LNA PTT status, error messages
