Pawlan Communications

Pawlan Communications specializes in system analysis, circuit design, product development, prototype construction, testing, and small manufacturing runs. We can provide you with one consultant or a team of consultants to solve problems or take charge of product development at your facility or ours. You always get high-quality work and a quick turn-around time. 

Business Services

Some of our areas of expertise include:
Amplifiers Wide dynamic range, low noise, and power amplifiers with frequencies from DC to microwave.
Filters Active and passive filters with frequencies from sub-audible to microwave.
Oscillators VCO, Crystal, low noise, and resonator-stabilized oscillators with frequencies from audio to microwave.
Radio Communication
Systems		 Wide dynamic range and low-power radio communications systems. Receivers, transmitters, full and half duplex using voice, data, and broadband modes. All radio communications systems span frequencies from HF to microwave. Design and testing to meet FCC parts 15, 90, 97 as needed is also available. 
Instrumentation Low-cost instrumentation solutions for medical or special-purpose instruments.
Analysis or Technical Review
of Existing Designs		 Independent design review, computer simulations using SPICE or the Ansoft Serenade Non-Linear Suite, and models created for package parasitics.
Training Group or individual training in your facility on RF topics or computer simulation.
Printed Circuit Board Layouts Double-sided or multilayer boards built from glass epoxy (FR4), glass teflon, pure PTFE, or ceramic. Boards can be optimized for size (sub-miniature or ultra-high density), analog/RF/microwave performance, and minimized cross-talk or ringing.
Analog and RF Testing with Performance Verification Lab with test equipment for regular testing, and GPIB programming for automated testing.
Rapid Component Procurement Most SMT passives, and many Transistors, ICs, and Diodes in stock. Accounts with nearly all major electronic distributors in Northern California. Please note that I do not sell components; these are only for use in rapid prototype development.

About The Owner

RF design Jeffrey Pawlan began studying electronics at age 12, and has been a licensed amateur radio operator since 1960. After graduating UCLA where he studied engineering, chemistry, physics, and music, he began his career in electronic engineering. He has worked for a number of prominent companies in both Northern and Southern California on a permanent or consulting basis and became a full-time independent consultant in 1992.

In 1991 he founded Pawlan Communications to provide independent consulting services to large and small companies all over the United States. In this capacity, he has designed many wireless LANs, RFID tag systems, and handheld products. Currently, his favorite research areas are low noise wide dynamic range amplifiers, and low phase noise oscillators.
