Waveguide Bends
Fairview Microwave’s lines of precision waveguide bends are widely used in applications such as high efficiency RF, microwave and mm-wave transmissions, satellite and military communications, radar, telecom, instrumentation and test benches. In waveguide systems that require a signal to turn or bend 90 degrees, Fairview’s waveguide bends are used to facilitate that bend or turn without degrading the transmission signal. These WG bends operate from 5.85 GHz to 90 GHz across 12 frequency bands and are available in sizes from WR-12 to WR-137. This family of waveguide bends also boast low loss and VSWR as low as 1.08:1 and are available in both E-plane and H-plane configurations. They are constructed using gold plated, oxygen free hard copper (OFHC) or painted copper alloy depending on the model and are also offered with either a UG-style flange per the military standard or a CPR-style flange. Many models are RoHS compliant.

Varactor Tuned Gunn Oscillators
Varactor tuned Gunn oscillators utilize high performance GaAs Gunn diodes and various cavity configurations to deliver moderate output power with low AM/FM noise and harmonic emissions. The oscillators are specially designed for a broader tuning bandwidth and an electrical tuning capability. The standard offering covers the frequency range of 8.2 to 110 GHz and features a self-locking set screw for fine frequency setting. While standard models offer a waveguide interface, a coaxial interface is also available. The performance of the oscillator can be further enhanced by adding an isolator, Gunn oscillator modulator/regulator, and temperature heater.

Gaussian Optics Lens Antennas
SAG-1441544002-06-S1
Gaussian optics lens antennas are offered with either a circular or rectangular waveguide interface. While Gaussian optics lens antennas 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. Gaussian optics lens antennas are designed and constructed to offer high efficiency, low side lobes and a rugged mechanical configuration. A corrugated feed horn and dielectric lens allow these antennas to form well-defined Gaussian beams. Additionally, the dielectric lens provides phase error corrections and serves as a radome to protect from environmental conditions.
