Scalar Feed Horn Antennas
-
Scalar feed horns are offered as both standard and custom build models with either a circular or rectangular waveguide interface. While scalar feed horns with a rectangular waveguide interface can only support linear polarization, models with a circular waveguide interface can support various polarization types including horizontal, vertical, left-handed circular, and right-handed circular polarization for broader applications. The standard models operate across the full waveguide band and offer 17 dBi nominal gain, 25 degrees half power beamwidth and a -28 dB side lobe level at center frequency. The below standard offering covers the frequency range of 8.5 to 140 GHz. However, other frequencies or gain values are also available.

Coaxial Programmable Attenuators
-
Coaxial attenuators are constructed with passivated stainless steel for durable use in both engineering labs and production line environments. These coaxial attenuators are designed and manufactured for low VSWR, low insertion loss and high attenuation value accuracy. The standard offering covers the frequency range of DC to 110 GHz and includes various interface options from 2.4 mm to 1 mm connector types as well as both male and female interfaces. The power handling of standard models is 0.5 to 1 watt continuous wave (CW). Higher power handling levels and different attenuation values and connector types from those listed below can also be requested.

Full Band Phase Shifters
STP-18-10-M2
-
Full band phase shifters are micrometer-driven, waveguide-based phase shifters. The configuration of the micrometer-driven phase shifters is similar to that of level setting attenuators, where the phase shifting is caused by an E-plane dielectric insert in the rectangular waveguide. The amount of phase shifting is directly dependent on the volume of the insert. The VSWR and the insertion loss of these phase shifters are dependent on the frequency. The below standard offering covers the frequency range of 18 to 110 GHz and a phase shifting range of 180 degrees. These micrometer-driven phase shifters are typically used to introduce a certain amount of phase shifting when the absolute number is not a focus.

Frequency Extenders
-
A frequency extender is an electronic device that allows high-fidelity analog audio to be sent over regular POTS telephone lines, without the loss of higher audio frequencies. It is an extended concept of a telephone hybrid.

Lens Antennas
-
A lens antenna is a directional antenna that uses a shaped piece of microwave-transparent material to bend and focus microwaves by refraction, as an optical lens does for light.[1] Typically it consists of a small feed antenna such as a patch antenna or horn antenna which radiates radio waves, with a piece of dielectric or composite material in front which functions as a converging lens to collimate the radio waves into a beam.[2] Conversely, in a receiving antenna the lens focuses the incoming radio waves onto the feed antenna, which converts them to electric currents which are delivered to a radio receiver. They can also be fed by an array of feed antennas, called a focal plane array (FPA), to create more complicated radiation patterns.

Rectangular Horn Antennas
-
SAGE Millimeter wave rectangular gain horns, also called pyramidal gain horns, are offered as both standard and custom models with a rectangular waveguide interface. The pyramidal gain horns only support linear polarization. With a calibrated gain chart, these horns can be used to measure the gain of other antennas by comparing the generated signal levels of both. For this reason, these horns are also referred to as standard gain horns. The listed models offer 23 dB nominal gain, 10/11 degrees typical half power beamwidth and 14 dB/30 dB typical side lobe levels at the center frequency of the band. These horns cover full waveguide bandwidths within the frequency range of 8.2 to 170 GHz. In addition to the models listed below, models with 10, 15, 20 and 25 dB gain and other frequency bands are also available.

Cassegrain Antennas
-
In telecommunications and radar, a Cassegrain antenna is a parabolic antenna in which the feed antenna is mounted at or behind the surface of the concave main parabolic reflector dish and is aimed at a smaller convex secondary reflector suspended in front of the primary reflector. The beam of radio waves from the feed illuminates the secondary reflector, which reflects it back to the main reflector dish, which reflects it forward again to form the desired beam. The Cassegrain design is widely used in parabolic antennas, particularly in large antennas such as those in satellite ground stations, radio telescopes, and communication satellites.

Dual Polarized Scalar Feed Horn Antenna, 24 to 42 GHz, 15 dBi
SAF-2434231535-358-S1-280-DP
-
Model SAF-2434231535-358-S1-280-DP is a dual polarized, WR-28 scalar feed horn antenna assembly that coversseveral popular 5G bands in the frequency range of 24 to 42 GHz. The antenna features an integrated orthomode transducer (OMT) that provides high port isolation and cross-polarization cancellation and a broad band scalar horn that provides low side lobe levels.

Wide Mechanical Tuning Bandwidth Gunn Oscillators
-
Wide mechanical tuning bandwidth Gunn oscillators utilize high performance GaAs Gunn diodes and various cavity designs to yield near full band frequency coverage. Unlike dual-tuner oscillators, frequency and power optimization are accomplished by a single micrometer. Furthermore, these oscillators can be modified into electrically tunable oscillators by replacing the micrometer with an electrical actuator. The wide tuning bandwidth of these oscillators offers a low cost, high performance means of signal generation, making them ideal test sources for labs and antenna ranges. While standard models offer a waveguide interface, a coaxial interface is also available. When used with a Gunn oscillator regulator/modulator (SOR series), these oscillators can produce AM or FM modulated signals for many test applications.

Frequency Down Converters
-
In digital signal processing, a digital down-converter (DDC) converts a digitized, band-limited signal to a lower frequency signal at a lower sampling rate in order to simplify the subsequent radio stages.

Volume Production Oscillators
-
Volume production oscillators utilize either high performance GaAs Gunn diodes with high Q cavity designs or state-of-the-art FET devices with dielectric resonators to yield excellent phase noise and stability. These oscillators are free running with extremely high frequency and power stability. The oscillators are generally designed and manufactured for fixed frequency applications. However, fine frequency adjustments can be achieved by mechanically tuning the provided self-locking screw. While the below standard models are offered for immediate production release, custom models are also available.
