The Collins HF-2050 is the latest in a long line of state-of-the-art hf communications equipment. Introducing Digital Signal Processing techniques to the hf communications market, the HF-2050 Receiver provides superior performance, high reliability, and operational flexibility not found in contemporary receivers.


The HF-2050 Receiver is small in size (5.25 inches in height). The key pad and interactive display have been designed to provide the operator with quick access to all operating parameters of the receiver. Immediate recall of 30 preset operating channels is at the fingertips of the operator.

Hardware intensive amplifiers, filters, and control loops have been replaced with digital signal processing using large scale integrated circuits (LSI), resulting in accurate and stable performance. First line maintenance levels are easily accomplished with the Built-In-Test Equipment (BITE) which isolates faults to the module level. The simplicity of digital signal processing circuitry facilitates fault isolation to functional circuits with the use of extensive auxilary test equipment.

Front-end linearity is enhanced by the high performance front-end (+25 dBm third order intercept) and ultralow noise synthesizer. Optional features such as noise blanker, independent sideband, and high stability frequency standard are available to complement the superior performance of the HF-2050 Receiver.

The following is a brief summary of the outstanding features:

  • Digital signal processing technology.
  • Compact 5.25-inch panel height.
