TTE Filters

What TTE Filters does

TTE Filters is a US-based custom manufacturer of passive RF and microwave filters, founded in 1956 and headquartered in Arcade, New York. The company designs and manufactures filters using established passive LC (inductor-capacitor) topologies — including Bessel, Butterworth, Chebyshev, Combline, Elliptical Function, and Gaussian configurations — covering frequencies from 500 Hz to 26 GHz. TTE operates as a subsidiary of iNRCORE, LLC, sharing corporate ownership with sister brands Microwave Circuits (MWC) and Instec Filters, and serves a horizontal base of OEMs and electronics manufacturers worldwide in communications, signal processing, telemetry, and test applications.

The company's product portfolio spans band pass, low pass, high pass, notch, bias tee, diplexer, multiplexer, triplexer, EMI/RFI, and equalizer filters, alongside specialty low-THD variants. Most products are custom-built to customer specifications with a standard 2-week lead time, expedited options of 3-5 days on select items, and an in-stock LC9S Chebyshev lowpass series available for same-day shipment. Pricing is quote-based and not publicly disclosed, with products being non-returnable due to their custom nature.

TTE's go-to-market combines direct enterprise sales (sales engineers responding via speed-quote forms, phone, and email) with indirect channels including a global network of distributors and manufacturer representatives. Marketing is anchored on the company website with product datasheets, application notes, filter facts educational content, and social media presence on LinkedIn, Facebook, and X. All products are manufactured in the USA, and the company emphasizes 50+ years of design expertise, rapid quote turnaround, and inventory management tools as primary differentiators.

Products and services

• Band Pass Filters RF band pass filters that pass a specific frequency range while attenuating frequencies outside that range, available in Bessel, Butterworth, Chebyshev, Combline, Elliptical Function, and Gaussian topologies covering frequencies from 500 Hz to 26 GHz. Designed for OEMs and electronics organizations integrating filters into RF and microwave systems.
• Low Pass Filters Low pass filters that pass low-frequency signals while attenuating high-frequency signals above a specified cutoff frequency, including high-power Chebyshev variants handling up to 300 Watts and frequencies from 600 kHz to 600 MHz. Used by OEMs for frequency selection and signal conditioning.
• High Pass Filters High pass filters that pass high-frequency signals while attenuating low-frequency signals below a specified cutoff frequency, available in Butterworth, Chebyshev, Elliptical Function, and custom TTE designs. Built for RF system integrators requiring low-frequency rejection.
• Notch Filters Band-reject (notch) filters that attenuate a specific range of frequencies while passing frequencies outside that range, available in Chebyshev topology. Used by OEMs to suppress narrow-band interference or unwanted frequency components in RF and microwave systems.
• Bias Tee Filters Three-port networks used to insert or extract DC bias current or voltage from an RF signal without affecting the RF signal itself, with superior broadband performance, low insertion loss, minimal return loss, and flat gain response. Available in High Current, High Frequency, and Standard versions for OEM and test-system applications.
• Diplexer Two-port network that combines or separates signals at two different frequency bands. Used by OEMs integrating multi-band RF systems that require frequency-domain signal routing.
• Multiplexer Multi-port network that combines or separates signals at multiple different frequencies, available for any frequency from 10 kHz to 26 GHz. Includes high-power networks up to 600 Watts and airborne versions up to 75 Watts for OEM applications.
• Triplexer Three-channel frequency separation device that combines or separates signals at three different frequency bands. Designed for OEMs and system integrators needing multi-band signal routing.
• EMI/RFI Filters Electromagnetic interference and radio frequency interference filters for EMI/RFI suppression, available in Hermetic, Resin Sealed, and Solder-In configurations. Used by OEMs and electronics manufacturers to meet EMC and signal-integrity requirements.
• Equalizer Frequency response equalization devices used for signal conditioning in RF and microwave systems. Built for OEMs needing to flatten or shape frequency response across a band.
• Low THD Filters Specialty filters designed for applications requiring low total harmonic distortion (THD) performance, including audio and high-fidelity signal-path applications. Targeted at OEMs and test/measurement users needing minimal harmonic distortion.
• LC9S Series (Chebyshev Low Pass from Stock) 9-pole Chebyshev Lowpass Filters offered from stock for same-day shipment, with 12 distinct part numbers at specific -1dBc passband frequencies from 30 MHz to 6 GHz. Built for OEMs and buyers needing off-the-shelf lowpass filters without the wait of a custom build.
• LC17 and HC17 Filters New Chebyshev Lowpass (LC17) and Highpass (HC17) filter series offering 'Brick Wall' performance similar to an Anti-Aliasing Elliptical Function filter, covering 1 MHz to 7 GHz. Designed for audio-to-digital and digital-to-audio conversion (ADC/DAC) test setups.

Direct peers

• Mini-Circuits: Mini-Circuits is one of the largest manufacturers of passive RF, microwave, and millimeter-wave components, including a deep catalog of LC, ceramic, and cavity filters. It competes most directly with TTE in custom and semi-custom bandpass, lowpass, and highpass filters for OEM customers.
• Reactel: Reactel is a US-based custom manufacturer of RF and microwave filters, diplexers, multiplexers, and switched filter banks for military, aerospace, and commercial OEM customers. It competes directly with TTE in low-volume, high-mix custom filter programs.
• RLC Electronics: RLC Electronics designs and manufactures RF and microwave filters, multiplexers, and switched filter assemblies for military, aerospace, and commercial applications. Its custom-engineering approach to bandpass, lowpass, and highpass filters is closely comparable to TTE's model.
• Knowles Precision Devices: Knowles Precision Devices (a Dover company) manufactures custom RF and microwave filters, including ceramic, LC, and cavity designs, for defense, aerospace, and commercial markets. It directly competes with TTE in high-reliability custom filter programs and shares a similar OEM focus.
• Microwave Circuits (MWC): Microwave Circuits (MWC) is a sister brand under iNRCORE alongside TTE Filters, producing RF and microwave passive components. It is the most direct internal comparable for TTE given shared ownership and product line overlap.
• Lark Engineering: Lark Engineering manufactures custom RF and microwave filters including LC, cavity, and ceramic designs for communications and defense OEMs. Its product breadth and custom-design focus are highly comparable to TTE's positioning.
• Anatech Electronics: Anatech Electronics designs and manufactures custom RF and microwave filters, multiplexers, and passive components for communications, defense, and test applications. Its product mix of bandpass, lowpass, highpass, and notch filters closely mirrors TTE's catalog.

Broad incumbents

• Qorvo: Qorvo is a major RF semiconductor company supplying integrated front-end modules that include SAW, BAW, and integrated passive filter solutions. While Qorvo operates in a different technology tier (active ICs), its integrated solutions represent a competitive threat to TTE's discrete passive filter business.
• API Technologies / Spectrum Control: API Technologies (now Spectrum Control) is a larger diversified manufacturer of RF filters, EMI/RFI components, and integrated microwave assemblies for aerospace and defense. It overlaps with TTE in custom filters but serves a broader portfolio of mission-critical applications.
• Murata Electronics: Murata is a global leader in passive electronic components including a large portfolio of RF filters (SAW, ceramic, LC) for mobile, communications, and IoT applications. It is a broad incumbent competing with TTE at the high-volume end of the filter market.
