Off-the-Shelf Solutions

Pole/Zero offers a catalog of readily available tunable rf bandpass filters and low noise amplifier (LNA) modules for integration into your system, as well as Integrated Cosite Equipment (ICE) to solve a particular interference issue.  Product offerings range from simple two-pole devices to highly sophisticated designs that incorporate high Power Amplifiers, AC/DC and DC/DC converters, circulators, harmonic filters, and digital interfaces compatible with many popular transceivers.  Applications range from automated test systems to sophisticated radar systems; from cleaning up local oscillators to protecting critical communication and data links.  Our range of products is summarized below:

• Off the shelf, high dynamic range system components
  • Rapidly tunable, 2-pole Butterworth filters of varying signal handling characteristics
    • Bandpass
    • Notch
    • Low Noise Amplifiers
    • SATCOM diplexers
• Custom Integrated Cosite Equipment (ICE), for more challenging cosite communications interference mitigation systems
  • Multi-band Integrated Cosite Equipment
    • Preselectors for receiver protection
    • Postselectors for transmit spectral enhancement
    • Filter/power amplifiers

We also have extensive thermal and vibration capability to conduct stringent Environmental Stress Screening (ESS) on our products prior to delivery to ensure identification of any latent defects.  Contact us to learn how our COTS RF interference mitigation solutions can enhance your RF system. 

Cosite Analysis

Pole/Zero has amassed a considerable database of modern transceiver vulnerabilities to cosite communications effects.  Armed with this database and communications platform characteristics such as antenna isolation and operational requirements, we have the expertise to simulate the cosite interference effects and apply cost effective mitigation techniques.

Engineering Design, Development and System Integration

Cosite mitigation equipment design has, at its core, the minimization of noise effects while maximizing the ability of circuits to accommodate large signals in a linear fashion without distortion.  Achieving these disparate capabilities within a single piece of equipment requires a very skilled and experienced engineering team with state-of-the-art tools at their command.  In addition to extensive design and development tools, we have on-site capability to conduct qualification testing for thermal, humidity, vibration, and shock environments.  The Pole/Zero engineering team is available to assist your team in the development of cosite mitigation system solutions or any application where high dynamic range circuit techniques are required.
