We design and manufacture frequency counters and VXI and PXI microwave products. We are a wholly owned subsidiary of National Instruments Corporation (Nasdaq: NATI), and we are located in the heart of California’s Silicon Valley.

Phase Matrix Founders Mr. Charanbir Mahal (left) and Mr. Pete Pragastis (right)In 1999 former employees of EIP Microwave, Inc. purchased key assets of EIP to form Phase Matrix, Inc. EIP, a well-established and long-time manufacturer of RF and microwave test-and-measurement (T&M) instruments, was a pioneer in the industry, introducing the first automatic frequency counters in 1976. In their senior technical roles at EIP, the founders of Phase Matrix contributed significantly to EIP’s most innovative products, including VXIbus synthesizers, counters, and downconverters. Phase Matrix continues to support the large installed-base of EIP® brand products.

An Early EIP AdvertisementIn 2004, we expanded our product offering by forming a microwave components group, which is led by Dr. Amarpal "Paul" Khanna, a well-known leader in the RF and microwave industry.  National Instruments re-branded this product line in 2014 to NI Microwave Components, and the team continues to develop and manufactures a broad spectrum of RF and microwave components such as wideband voltage-controlled oscillators (VCOs), digitally tuned oscillators, phase-locked Drs. Khanna (left) and Chenakin (right) are major contributors to the Phase Matrix success storyoscillators, and high-performance integrated microwave assemblies up to 67 GHz and--in some cases--beyond. Products produced by the NI Microwave Components group are used in military and commercial instrumentation and telecommunications for major military-contracting companies such as Lockheed Martin and Northrop Grumman and innovative commercial companies such as Anritsu and LeCroy. 

In 2006, Phase Matrix formed a frequency synthesis group, led by Dr. Alexander Chenakin (a.k.a. the Frequency Synthesis Guru).  The popular QuickSyn line of fast-switching synthesizer modules that are based on a unique and revolutionary phase-refining technology are produced by Chenakin's team. In 2014, QuickSyn products were re-branded to NI Microwave Components products.

Phase Matrix's Family of PXI Downconverter Modules in 2007In 2007, Phase Matrix announced the introduction of its innovative family of small form-factor PXI modules for use in portable and transportable synthetic instrument applications. Our family of PXI downconverter modules can be configured seven different ways to cover frequency ranges from 100 kHz to 2.9 GHz, 2.7 to 26.5 GHz, and 100 kHz to 26.5 GHz for T&M solutions.

National Instruments (NI) acquired Phase Matrix in 2011 to bring key RF talent, technologies, and manufacturing capabilities to NI. In 2013, Phase Matrix relocated from San Jose to Santa Clara, CA to share a 50,000 square foot facility with two other NI groups that were located in Silicon Valley. The new site has a large dedicated R&D lab, an updated and upgraded manufacturing facility, and a professional NI training center. The co-location fosters collaboration among NI's engineering teams as well as results in many other benefits.
