Pioneering the World’s First Technological Breakthrough in Electronic Filter Miniaturization and Integration in Zero-Cost Air Dielectric Medium
1 MHz – 100 GHz
milliwatts to kilowatts
[ About ]■
Dynamac Microwave has pioneered Multilayer-Air filter, the world’s first and only filter miniaturization and manufacturing technology for fabrication of radio frequency (RF) filters in zero-cost air dielectric medium. This technology breakthrough, enabled by Dynamac Microwave’s proprietary Fractional Element Filter Architecture (FEFA) algorithm, has staggering economic, scientific, technological, and environmental implications. Dynamac Microwave’s groundbreaking FEFA Multilayer-Air filter technology impacts the entire RF filter industry and market by covering the entire frequency spectrum from 1 MHz to 100 GHz and supporting all applications from milliwatts to kilowatts. It reduces size and weight of high power filters by 60-75% and as much as 90% for sub-6 GHz 5G infrastructure and aerospace & defense systems; it improves signal transfer efficiency by 30-50%, and reduces cost by 60-70% across the board.
[ innovations ]Technology Overview
The Indispensable Role of RF Filters
What exactly is this technology that drives our current day-to-day communications infrastructure?
RF filters are used in every wireless and communication device and system in existence
Billions of RF filters are sold every year
RF filters allow a desired frequency/signal to pass and attenuate all others supporting applications including
Spectrum management and Signal Conditioning
Mitigation of interference and noise
Filters vary from large cast aluminum and CNC machined units for cellular infrastructure applications to chip filters for mobile phones and a wide range of consumer devices
$100’s to sub $.50
4G smartphones use more than 40 RF filters
The number of RF filters in 5G smartphones is projected to exceed 70
The current market size of all RF filter products is estimated to be ~$15 Billion
What are the pain points inherent in legacy systems?
The Challenges with Current RF Filter Offerings
Large Size
Air cavity and waveguide filters are bulky particularly at low frequencies
High Weight
High power air cavity filters can weigh as much as 30 pounds
High Insertion Loss (Increased Power Consumption)
Signal attenuation through filter = energy waste
High Cost
High performance low-loss RF air cavity/waveguide filters cost in the hundreds of dollars
Low Power Filters: Limited Frequency Range, Limited Bandwidth, High Insertion Loss, High Cost
BAW and SAW filters have reached their performance limit:
BAW (Range Limit: 6 GHz) (Power Handling: 1W)
SAW (Range Limit: 2 GHz) (Power Handling: <1W)
High Insertion Loss
Multilayer Ceramic and PTFE Filters
Range Limit: 10-15 GHz
High Insertion Loss
High Cost
What makes Dynamac Microwave’s proprietary FEFA algorithm the best solution for challenges in the RF filter marketplace?
The Holy Grail of RF Filters
65-90% smaller and lighter weight than current expensive high power machined air cavity and waveguide filters.
50-75% lower cost than current high power machined air cavity and waveguide filters.
40-50% lower cost than SAW, BAW, and multilayer ceramic and PTFE filters.
30-65% lower insertion loss than current filters (SAW, BAW, multilayer ceramic and PTFE, air cavity, and waveguide filters).
