Introducing Our Four Business Units

From its rich COTS component foundation, Eravant has developed a wide variety of standalone test equipment and partnered with key industry leaders to offer cost-effective test solutions for covering mmWave and sub-THz frequency bands up to 330 GHz.

Antenna Measurement Services

Eravant offers a range of standard antenna measurement services including gain, 2D, and 3D patterns. Frequency step size, operating bandwidth, and polarization settings can be specified by request.

LN2 Noise Source Calibration

Eravant waveguide noise sources are calibrated in-house using a cold reference termination that is cooled with liquid nitrogen. Eravant offers calibration services for waveguide banded noise sources up to 220 GHz and recommends repeating calibrations annually.

Near Field Range Testing

Eravant is one of the very few millimeter wave antenna manufacturing companies in the United States that can design, manufacture, and test large aperture microwave and millimeter wave antennas up to 110 GHz. In particular, Eravant has experience in production testing of large aperture Cassegain reflector antennas up to 2.4 m in diameter for Q/V-Band LEO/ GEO ground station applications.

Noise Figure Testing

Eravant offers precise and reliable noise figure testing services for amplifier components, employing the Y-factor method as the most common approach. This method uses a calibrated noise source that switches on and off to characterize the noise figure accurately.

Phase Noise Measurement Services

Eravant offers industry-leading phase noise testing services, utilizing real-time cross-correlation measurements for exceptional accuracy. Through a partnership with Holzworth, we have developed in-house test capabilities for precise phase noise measurement and actual noise floor measurement.

The 1 mm connector supports the frequency range of DC to 110 GHz operation and can be stretched to cover DC to 130 GHz. There are many different types of connectors. For this presentation, only sparkplug and cable connectors are included.

STO Configuration Guide

Eravant’s VNA frequency extenders are used to increase the reach of coaxial Vector Network Analyzers to millimeter-wave and sub-THz frequencies. They are compatible with VNAs produced by major OEMs including Anritsu, Copper Mountain Technologies, Keysight, Rohde & Schwarz and others.

Uni-Guide™ Practical Waveguide Connector

The idea was from Eravant's own Product Development. There were too many product interface variations, product packages to manage, and excessive product development cycle time. It is used in the same way as the coaxial connector. It is field replaceable as long as glassbead is used and allows for various RF interfaces.

Waveguide Quick Connects

The idea was from Eravant’s own Testing Experience. Using waveguide screws to make the test set and DUT connections can cause scratches and marks on DUT surface. Two models are offered to cover operating frequency from 33 to 1 THz or beyond. We only need to use two thumb screws to make the waveguide connection easily reliable.

Dual Pol Antenna Applications for 5G

This presentation introduces Eravant's dual-pol antennas offering in broadband for 5G System Applications. Although the standard models are specified for full waveguide band operations, they can cover many Extended Millimeter Wave 5G Bands.

ACCESS Synthesized Signal Generator

Eravant offers a series of portable, touchscreen and USB controlled synthesized signal generators under the ACCESS brand. They are designed to complement Eravant’s ACCESS series downconverter, frequency extender, and noise source modules for millimeterwave signal generation or frequency extension up to 330 GHz for various test equipment such as spectrum analyzers and noise figure analyzers.

ACCESS Radar Target Simulator

Eravant offers a series of doppler radar target simulators that operates in WR-42 to WR-10 waveguide banded frequencies. The target simulators utilizes a single-sideband-modulator to modulate the incoming signal transmitted by the radar under test and sends back either a higher or lower band signal through a circulator. Eravant also offers an ACCESS series function signal generator designed for use with the target simulators.

ACCESS mmWave VNA

For decades, engineers working above 50 GHz have faced the same compromise: bolt frequency extenders onto a general-purpose VNA and accept the cost, complexity, and fragility that come with it. Eravant and Copper Mountain Technologies set out to change that. The result is the mmWave VNA — a dedicated solution engineered specifically for millimeter-wave S-parameter characterization, anchored by Copper Mountain’s Model BFx-02 base VNA and paired with Eravant’s millimeter wave signal-chain expertise.

ACCESS mmWave Up Downconverter

A millimeter-wave communication link is built on two frequency translation stages that have to agree with each other: an upconverter that places the baseband or IF signal cleanly onto the radio-frequency carrier, and a downconverter that brings it back down. Eravant’s ACCESS mmWave Up/Downconverter family delivers both stages as matched, turnkey instruments. The STV upconverter takes the transmit IF and translates it on-band; the STC downconverter receives the RF and recovers the IF.

ACCESS mmWave Synthesizer

Millimeter-wave test benches, antenna ranges, and emerging 6G research setups all share one persistent need: a clean, programmable signal source that reaches deep into from 45 to 330 GHz seamlessly. Eravant’s ACCESS mmWave Source family answers that need by offering a portable, touchscreen-operated, low-phase noise signal source — turnkey, remote-programmable, and lab-grade across 45 GHz to 330 GHz from a single bench-friendly footprint.

ACCESS mmWave Noise Figure Test Set

Accurate noise figure measurement above 26.5 GHz demands more than a stand-alone noise meter or analyzer. Eravant brings everything together in one all-in-one solution — the compact down converter with embedded low-phase-noise synthesizer (STL-SG-022203-S1), and LN₂ calibrated noise source — pre-matched and factory calibrated as a turn-key Y-factor measurement chain that drops directly into any standard noise figure analyzer, making millimeter-wave noise figure testing more accessible, more convenient, and ready to use out of the box.
