Improved Usability
  • New easy touchscreen
  • New intuitive WebUI
  • New graphics and event logging
  • Simplified Automatic Level Control (ALC)

Enhanced Performance
  • Reduced intermodulation
  • Reduced gain variation
  • Halved warm-up time

Easy to maintain

  • Upgrades with Linearizer and block up-converter (BUC) possible (Retro-Fit)

Form Fit & Function
  • M&C and dimensions identical to HPA 2xxx & 3xxx series

“ND SATCOM’s quality engineering and flexible design enable customers from broadcast to medicine to choose among multiple off-the-shelf HPA variants – different power classes, frequency bands, chassis types, and BUC and Linearizer options - with quick delivery time,” said Michael Weixler, Director of Product Management & Training. “We have also refined size and performance, offering the smallest indoor chassis (3U in all power classes), 3dB less fan noise and 10% less power consumption. Both form and function are critical to how we innovate and deliver on our customer promise of installing reliability.”

ND SATCOM has a longstanding relationship with the German company WORK Microwave and offers WORK’s superior quality L-band BUC as an option. For customers who opt for ND SATCOM’s Linearizer, it provides a larger operating power range with typically 1dB less back-off required. These additions further enhance overall power and performance.
