ERAVANT
ModelSWD-5038531040H-15-SB is a V band, three-port waveguide directional coupler that delivers a 10 dB nominal coupling level and 30dB minimum directivity across the full waveguide band from 50to 85GHz. The three-port coupler uses a traditional multi-holeand split block design to achieve a flat coupling level, high directivity, and low insertion loss. The interfaces of the coupler are WR-15waveguides with UG-385/Uflanges. Custom coupling levels are available under different model numbers.

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.

Full band waveguide detectors are GaAs beam lead Schottky diode-based detectors that are specially designed for millimeterwave network analyzer applications. With a proprietary circuitry design and careful diode selection, these zero-biased detectors exhibit high sensitivity and extremely flat output characteristics. The below standard offering covers the frequency range of 18 to 170 GHz and offers a 1 MHz video bandwidth and 1 MΩ video output impedance. The standard models also have the capacity to handle a maximum RF input power of up to +17 dBm. The RF interface of these detectors is a standard waveguide with an integrated Faraday isolator to improve the port VSWR. The output voltage polarity is negative and the connector type is a female SMA. Other configurations are offered as custom models.

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.

A modulator is an electronic circuit that superimposes a low-frequency (information) signal onto a high-frequency (carrier) signal for the purpose of wireless transmission. The reason for this is that higher frequency signals can be received using shorter aerials, which are more practical than longer ones. The information signal can be either analog or digital.

ERAVANT
A coaxial 2-way power splitter with a typical insertion loss of 1.2 dB at each output port and a typical isolation of 16 dB across the frequency range of 1 to 18 GHz. The power splitter has a nominal power handling of 30 W (CW) and a typical amplitude unbalance of ±0.4 dB. The return loss for all ports is 13 dB typical. The RF connectors of the power splitter are female SMA connectors.

ERAVANT
2-way power divider that operates from 220 to 330 GHz. The power divider offers a typical insertion loss of 2.3 dB and typical isolation of 20 dB. All ports are well-balanced and in-phase for power dividing or combining applications across the band. The power divider is configured as a right-angle package with WR-03 waveguides and UG-387/U-M anti-cocking flanges at all ports.

Dielectric resonator oscillators (DRO) are free running oscillators that utilize state-of-the-art planar circuits, three-terminal devices and dielectric resonator technology to generate high-quality microwave signals with excellent frequency stability. In addition, these oscillators are equipped with an internal voltage regulator that further improves the frequency stability by isolating the external bias pushing and modulation. In general, these oscillators are fixed. However, a small mechanical or electrical tuning range can be achieved by use of a self-locking screw or an integrated Varactor diode. The standard offering covers the frequency range of 2 to 40 GHz. While standard models are equipped with female SMA and K connectors at the RF port, other RF interface options are also available.

Phase locked oscillators (PLO) utilize state-of-the-art planar circuits, three-terminal devices and dielectric resonator technology to generate high-quality microwave signals at lower frequencies. Frequency multipliers, amplifiers and filters are used to extend the low frequencies for higher frequency requirements. The standard offering covers the frequency range of 2 to 110 GHz and provides both internal and external reference options. The frequency stability and phase noise are dependent on the oscillator reference type.
