NuPower Xtender™ SCISR-20 Tri-Band Bidirectional Amplifier

Product Number: NW-BA-SCISR-20-M02 Product Type: Tags ,

The NuPower Xtender TM SCISR-20 Tri-Band Bidirectional Amplifier is a unique and versatile amplifier designed to support secure CDL ISR (SCISR) software-defined radio communications but can be used in any L-, S-, and/or C-band application.  The SCISR-20 simultaneously provides over 20 watts of RF transmit power, over 15 dB of receive gain, and features auto-sense T/R switching.

Product Description

Designed to Support:

The NuPower XtenderTM SCISR-20 Tri-Band Bidirectional Amplifier is a 20-watt amplifier intended to simplify subsystem architecture with a compact form-factor offering in-band and cross-band bidirectional communication for improved link margin. Featuring auto-sense T/R capabilities with a 2-μs switching speed, the SCISR-20 automatically detects whether it is in transmit or receive mode in each channel, independent of the operational modes of the other channels.

This amplifier is designed to support secure CDL ISR (SCISR) software-defined radio communications as an easy-to-integrate addition to any ground or airborne terminal. While the SCISR-20 is designed to support these SCISR radios specifically, it can be used in any application requiring amplification in L-, S-, and C-band and can be customized for specific use-cases and unique requirements.

Small, compact, and rugged, the SCISR-20 is designed and built to last in the harshest of environments. Furthermore, NuWaves Engineering’s commitment to maintaining our AS9100D quality management system guarantees full materials traceability and quality accountability.

*Verified compatibility with radio OEM


The SCISR radio is a small (cell phone size), light-weight, digital data link designed to pass high capacity IP traffic in diverse spectral environments. Multiple vendors produce baseline SCISR radios – built upon the government owned BE-CDL specifications. All SCISR radios are interoperable with each other, as well as any BE-CDL compliant terminal.
Vendors offer additional enhancements, such as legacy To Be Sunset (TBS) waveforms in addition to the baseline BE-CDL waveforms. Due to the DoD mandate that requires all ISR data to be transported over CDL, this allows for smooth transition as the DoD moves towards full CDL compliance. One of the upcoming SCISR enhancements is spreading capabilities, allowing for operating in RF noisy and jammed environments. This also significantly decreases the RF emissions signature of the radio.
All SCISR radios utilize non-proprietary control interfaces ensuring the highest level of flexibility for the end user. Each SCISR radio goes through rigorous government testing before receiving certification, ensuring the highest level of compliance and reliability.

Each channel operates independent of one another. Here are a few examples of how the SCISR-20 could be operated:

  • Receiving on S-band while transmitting on S-band (half-duplex)
  • Receiving on S-band while transmitting on C-band (full-duplex)
  • Receiving on S-band while transmitting on L- and C-band (full-duplex)
  • Receiving on L-, S-, and C-band simultaneously
  • Transmitting on L-, S-, and C-band simultaneously
