Empower RF Systems Announce New HF Communications, Jamming Transmitter

High Power Amplifier: 2203

January 25, 2018

Empower RF is announcing the availability of their fielded Model 2203 high power amplifier, which operates from 1 to 30 MHz and delivers a minimum of 1 KW CW. The 2203 is capable of operating in multi-domain scenarios as a jamming or communications transmitter with any type of modulation (AM, FM, multi-tone, pulse, PSK, FSK and complex digital modulation).

The 2203 is designed with the latest 50 V LDMOS device technology, which lowers transistor count and reduces combining losses, increasing efficiency and reliability. In addition to the standard array of user-configurable, multi-mission mode settings, the amplifier offers user selectable "graceful output power degradation," backing down power to a safe operating level in case of component failure or excessive load VSWR.

Configurable Features

The Model 2203 has the following features:

Selectable Output Power Control

  • Automatic Gain Control (AGC)
  • Automatic Level Control (ALC)
  • Manual Gain Control (MGC)

Selectable Operating Modes

  • CW, FM, AM, CE
  • Digital Modulation
  • Multi-Carrier/Multi-Tone
  • Pulse Modulation
  • Gated Pulse, Blanking

Input Power Options

  • 220 V Single Phase
  • Three Phase Delta or Y (208 or 380 VAC)
  • 48 V DC

Protection

  • Load VSWR 3:1 (6:1 at 50 percent Psat)
  • Input Overdrive Protection
  • Thermal Overload Protection
  • Over and Under AC Voltage Protection
  • Out-of-Band Drive Protection
  • Selectable "Graceful Output Power Degradation"
  • Electronic VSWR Protection

The compact and durable rack-mount amplifier is the newest member of Empower’s Next Generation product portfolio. Sharing the family’s common hardware and software architecture, the Next Generation family is now being used in mission-critical applications covering 1 MHz to 6 GHz.
