Putting Innovation Within Reach
Product innovation at Trilithic has always been characterized by one thing: it’s practical. It
makes life easier for customers. It’s the natural result of listening to them. That philosophy
has been the driving force behind the company’s growth from its beginnings as a two-man
engineering team in 1986 to its current position as a global manufacturer with more than 130
employees.
A privately held company, Trilithic broadend its original RF and microwave component product
line by acquiring Filters manufacturer Cir-Q-Tel and instruments manufacturer Texscan, adding
broadband solutions to the product line. The company also expanded operations to Thailand in
2001, to meet increasing demand for its products in the growing markets of Asia.
As new communications applications continue to emerge, part of Trilithic’s business has
evolved into managing change—helping customers respond quickly to market opportunities
with innovative technology and individualized solutions. But the core value of Trilithic’s
business approach—listening to customers—hasn’t changed. Keeping that focus intact will
help provide better products in the long run and ensure continued growth for decades to come.
Trilithic is comprised of two major divisions:
Broadband Instruments
The company is best known for innovations in signal level measurement, leakage detection
and reverse path maintenance—like the use of Digital Signal Processing (DSP) technology,
which lets eld technicians upgrade their signal analyzers by simply downloading rmware.
Emergency Alert Systems
Trilithic’s EAS division is a leading supplier of homeland security government-mandated
emergency alert systems for broadband and other communication system providers. As
the communications industry continues its rapid evolution, Trilithic has begun offering
comprehensive systems and services to address a wide variety of emergency alert system
needs, including the design and architectural layout of complex analog and digital EAS
networks.
