Amplifier Research - Microwave Horn Antennas for RF & EMC Testing
AR Microwave horns take microwave coverage to a new level. Our broadband RF and microwave horn antennas are specially designed to compensate for the losses that typically occur in test systems as frequency increases. They exhibit increasing gain with increasing frequency, up to 50 GHz. AR microwave horn antennas can be used in shielded rooms or in free space.

More Product Information
The low frequency tuners are a unique product technology using MPT algorithms for low frequency wideband tuning. Three or more cascaded tuning sections use series transmission cables and parallel rotary capacitors.
The length of the cables and number of tuning sections are optimized for maximum tuning range over a given bandwidth. HLFT tuners use 6 tuning sections allowing second harmonic frequency tuning.
Focus provides the deepest portfolio of wideband fundamental and harmonic passive tuners. Passive impedance tuners generate controllable reflection factor (Impedance) across the smith chart over a given frequency range. Focus uses two basic technologies:
-
From 100MHz to 120GHz we use the slide screw technique in which a reflective probe is inserted into a low loss slotted transmission line.
-
For frequencies from 10MHz to 170MHz we use a lumped element technology, whereby variable capacitors are connected with optimized lengths of coaxial cable. To view our Low Frequency Tuners, Click Here!
Most Focus Passive Tuners use long lasting RF probes which are designed for optimal tuning accuracy and are free of spurious resonances. The combination of multiple probes provide ultra wideband coverage in one single tuner. All Focus Passive Tuners are LAN controlled and include on-board impedance synthesis firmware.

An impedance tuner is an apparatus, which generates controllable reflection factor (Impedance) over a certain frequency range. Focus uses two basic technologies:
a) For frequencies from 100MHz to 110GHz (and above) we use the slide screw technique (models Multi Harmonic MPT, wideband (fundamental) CCMT, harmonic rejection PHT), in which a reflective probe (slug) is inserted into the slot of a low loss slotted transmission line (slabline or waveguide).
b) For frequencies from below 10MHz to 170MHz we use a lumped element technology (models LFT), whereby variable capacitors are connected with optimized lengths of coaxial cable.
The MP Series of Field Monitoring Packages are combinations of AR Field Monitors and Field Probe Kits. Each package contains all the necessary equipment to make Field measurements.
Amplifier Research
Founded in 1969, Amplifier Research is a world-class source for broadband high power, solid state, RF amplifiers and microwave amplifiers, TWT amplifiers, log periodic antennas and high-gain horn antennas, plus EMC test equipment, software and field probes and monitors. Throughout its 50 years (and counting), AR has been responsible for a number of “firsts” which have transformed not only EMC and RF testing but also the industries and equipment affected by these tests. A sampling of these innovations includes:
- 10,000-watt tube amplifiers,100-watt solid-state • 100-1000 MHz instantaneous bandwidth Class A amplifier
- First production 16,000-watt solid-state linear amplifier from 10 kHz to 225 MHz
- 50,000-watt Class A power amplifier up to 225 MHz
- 0.7 to 6 GHz high-power Class A & AB amplifier
Additionally, they push the limits of state-of-the-art design and have ruggedized their products to make them virtually indestructible. AR amplifiers are fully tested to the extreme to ensure customers receive a product that is built to last.
