Since 1985, Zubiel RF Systems, Inc. has been supplying innovative RF products tailored to meet the specific requirements of its commercial and military customers. We specialize in the rapid design and development of wireless data links, frequency synthesizers, transmitters, receivers and RF modems.

Unlike other firms that provide only consulting services, Zubiel RF Systems offers a turnkey solution to produce finished prototypes or pilot production hardware meeting all of your specifications. You won't be left with a half-baked paper design requiring extensive modifications to achieve the results you want. We attain production worthiness by paying close attention to critical areas such as RF board layout, grounding, shielding and sources of noise. Every detail is thoroughly engineered to minimize production risks by optimizing performance stability, manufacturability and cost.

Complete, fixed-price design services are offered, from product definition and performance predictions through board layout, fabrication and testing of the final product. Give us a call if you plan to launch a new RF product design, or just need to improve an existing one: you won't be disappointed.

Here is a sample of our capabilities:

• RF Link and Path Loss Analysis: Accurately predict your operating range
• Spurious Response and Intermodulation Predictions: Stop interference before it starts
• Signal to Noise, Bit Error Rate and J/S Level Predictions: Know how much signal you really need
• Modulation Performance Analysis: Use the method best suited to your application
• Battery Life Prediction for Portable Equipment: Don't let the battery be the weak link in your system

• Receivers and Transmitters: Digital or analog, FM/FSK, frequency agile or crystal controlled
• Part 15 Unlicensed RF Data Links: Send voice or data via a miniature, low power wireless link
• QPSK/QAM Digital RF Modems: Bandwidth efficient transmission of high data rate signals
• UHF/L-Band Block Converters: Upconvert UHF CATV signals to the DBS receiver band
• PLL and DDS Frequency Synthesizers: Low spurious, wide tuning range designs from HF through S-Band
• Emergency Locator Beacons: Locate downded aircraft with a VHF/UHF beacon transmitter
• Spread Spectrum Data Links: Send high speed data over greater distances using direct sequence
• Broadband ECM Jammers: Thwart the enemy with a high powered noise source
• Crystal, L/C and SAW Oscillators: VCXOs and VCOs are our specialties
• Active and Passive Filters: Choose from a wide variety of filter topolgies
• Antenna Matching Networks: Efficiently couple energy to and from your antenna
• Embedded Controllers: Add smarts to your RF product with a single chip microcontroller

• Linear and Non-Linear Circuit Simulation using SPICE: Thoroughly "test" circuits before you build them
• S-Parameter Analysis of RF Circuits using STAR: Don't leave band edge performance to chance
• Specialized Filter Synthesis Programs: Optimize filter performance in both time and frequency domains
• Complex Filter Analysis Performed with Mathcad: Accurately predict amplitude response and group delay
• Specialized Frequency Synthesizer Simulations: Settling time, phase noise and spurious level predictions

• Fully Integrated Schematic Capture and PC Layout Software: Go from schematic to pc board in a flash
• Surface Mount and Through-hole Designs: Combine both technolgies for easiest manufacturing and lowest cost
• Single-sided or Multilayer: Use single sided boards for lowest cost, multilayer for highest density

MANUFACTURING, TEST & DOCUMENTATION

• Quick Turnaround Manufacture of Prototypes and Pilot Production Units: Deliverable hardware packaged the way you want it
• Well equipped RF Laboratory with Modern Test Equipment: RF and microwave test equipment
• EMI Testing: Know if you're meeting FCC requirements
