KR Electronics

What KR Electronics does

KR Electronics, Inc. is a designer and manufacturer of custom and standard RF and microwave filters, founded in 1973 and operating as a dedicated division of Networks International Corporation (NIC), a Kansas corporation. The company serves both military and commercial markets; named customers include major U.S. defense primes (Boeing, Honeywell, L3Harris, BAE Systems, Raytheon, Rockwell Collins, Cobham, ITT, Harris, SRC, Hittite), federal agencies (NASA, Naval Research Laboratory), and commercial technology firms (Qualcomm, Texas Instruments, Viasat). Headcount is in the 11-50 range and the company operates out of Overland Park, Kansas. Certifications include ISO 9001:2015 (valid through January 31, 2026), ITAR registration through DDTC, and IPC-certified operator training under J-STD-001 and related standards.

The product portfolio centers on seven core filter families totaling over 1,400 standard part numbers: bandpass filters (878 models, 220 Hz to 13 GHz), highpass filters (55 models), lowpass filters (296 models including active, passive, Bessel, and group-delay-equalized designs from 5 Hz to 3 GHz), notch/band-reject filters (103 models), diplexers (17 models), equalizers (20 models), and root cosine filters (31 models). KR Electronics applies more than 25 design methodologies — Butterworth, Chebyshev, Bessel, Elliptic, Linear Phase, Gaussian, Legendre, Transitional, Custom Pole Placed, and others — and offers packages including SMD, DIP, SMA, BNC, N, F, SIP, and PCB. All filters undergo 100% electrical performance testing, with MIL-SPEC testing (MIL-F-18327, MIL-STD-202, MIL-STD-810) available when required. The company also produces encapsulated, ruggedized filters for Positive Train Control (PTC) rail applications at 160/220/455/916 MHz.

Revenue is generated through one-time sales of custom and standard filters, all built to order rather than held in inventory. Pricing is quote-based; formal quotations precede orders and lead times vary by complexity, with prototype turnaround often within one week. KR Electronics sells directly via email, phone, and fax to both domestic and international customers, supplemented by authorized domestic distributors that do not stock product. There are no international distributors. No funding rounds, M&A activity, executive leadership changes, or disclosed revenue figures appear in the available data, and no AI/ML capabilities are present in the technology stack.

Core offering

KR Electronics designs and manufactures custom and standard RF and LC filters for commercial and military markets. The company produces over 1,400 standard part numbers spanning bandpass, highpass, lowpass, notch, diplexer, equalizer, and root cosine filters across frequencies from 5 Hz to 13 GHz. Filters are built to order using proprietary computer synthesis, with prototype turnaround often achievable within one week.

Product overview

KR Electronics designs and manufactures a comprehensive portfolio of RF and LC filters for military and commercial applications. The product line centers on seven core filter types: Bandpass Filters (878 standard models from 220 Hz to 13 GHz), Highpass Filters (55 models from 50 Hz to 2.9 GHz), Lowpass Filters (296 models including active, passive, Bessel, and group delay equalized designs from 5 Hz to 3 GHz), Notch/Band Reject Filters (103 models), Diplexer Filters (17 models), Equalizers (20 models), and Root Cosine/Root Raised Cosine Filters (31 models). All products are available in multiple package styles including SMD, DIP, SMA, BNC, N, F, SIP, and PCB. The company also offers custom filter design services using various topologies (Butterworth, Chebyshev, Bessel, Elliptic, Linear Phase, Gaussian, etc.) and manufactures specialized Positive Train Control (PTC) filters for rail transportation. Products are designed and manufactured in the USA, with ISO 9001:2015 and J-STD-001 certifications.

Broad incumbents

• API Technologies (now Spectrum Control): Provider of RF/microwave filters, power products, and electromagnetic solutions for defense, aerospace, and industrial markets. Overlaps with KR Electronics in defense/aerospace filtering and MIL-SPEC products, but with broader portfolio including integrated subsystems.
• Qorvo: Major RF semiconductor and filter supplier (including BAW/SAW duplexers and integrated modules). Competes with KR Electronics in RF filtering for defense and commercial wireless, but at vastly larger scale and with semiconductor-integrated solutions rather than discrete passive filters.
• Murata: Global leader in passive electronic components including RF filters and modules for mobile, IoT, and automotive. Overlaps with KR Electronics in filter technology but competes in high-volume, miniaturized commercial sockets where KR's custom build-to-order model does not address.
• TDK (including EPCOS): Manufactures a broad portfolio of electronic components including RF filters, duplexers, and signal conditioning products. Comparable as a filter vendor across defense and commercial markets, but at much greater scale and with catalog/automated production.
