ALLEN, TEXAS—On-demand microwave and RF components supplier Fairview Microwave is rolling out a waveguide Gunn oscillator that provides a source of microwave power with frequency and power stability while generating low-phase noise. The FMWGN1001 is designed to be used to transmit and receive oscillators for radio communications and as a local oscillator source that can be multiplied for higher mm-wave frequency test and measurement.

The FMWGN1001 is a K-band waveguide Gunn oscillator that generates a center frequency of 24.125 GHz and can be tuned up to +/- 1.0 GHz via a self-locking tuning screw. The modules high external Q and temperature compensation mechanism allows the oscillator to exhibit higher frequency and power stability, lower phase-noise and higher anti-load-pulling characteristics. Specs include -95 dBc/Hz typical at 100 KHz offset and frequency stability of -0.4 MHz/°C maximum. Output power is +10 dB minimum with power stability of -0.04 dB/°C maximum. Bias supply is +5V dc at 200 mA typical with an operating temperature range of -40°C to +85°C.

Fairview is now shipping the FMWGN1001 waveguide Gunn Oscillator.

ALLEN, TEXAS—Fairview Microwave has a new single pole double throw PIN diode adsorptive switch available for consumers, the FMSW2026. The new switch covers frequencies from 100 MHz to 67 GHz and is available in a coaxial package.

The FMSW2026 features broadband performance characteristics that include maximum input power handling of 0.5 watts, insertion loss of 6 dB typical, 10.5 dB maximum, and isolation of 65 dB typical, 40 dB minimum. J1 and J2 ports are terminated in 50 ohms when switched in the isolation state to absorb higher frequency signal reflections. TTL compatible driver logic circuitry is included for accurate switching control.

The design of the FMSW2026 is gold plated and has interface connections that include 1.85 female connectors for mm-wave transmission, solder terminals for DC voltages, and an SMA female connector for TTL logic control.

Fairview has the FMSW2026 in stock and available for shipping.

ALLEN, TEXAS—On-demand microwave and RF components supplier Fairview Microwave has launched a new line of waveguide bends that operate from 5.85 to 90 GHz across 12 frequency bands, from C band to W band. The bends are available in 30 models with a range in size from WR-137 to WR-12; all models are RoHS compliant.

The Fairview waveguide bends are used to protect the strength of the transmission signal in waveguide systems that require a signal to turn or bend 90-degrees. These new waveguide bends feature low-loss and VSWR as low as 1.08:1 and are available in both E-plane and H-plane configurations. The bends are also offered with either a CPR-style flange or a UG-style flange.

The new waveguide bends are now in-stock and are available for shipping. 

ALLEN, TEXAS—Fairview Microwave announced the release of their new digitally controlled programmable attenuators with performance up to 40 GHz and up to 60 dB attenuation range with 0.03 dB minimum step size. These programmable attenuators are commonly used in electronic warfare, military and space communication systems, radar and test and measurement applications.

Fairview’s digitally controlled attenuators perform the function of adjusting the amplitude of signal levels in RF, microwave, and millimeter-wave systems. The designs utilize PIN diode semiconductor technology that generates “extremely fast switching performance between attenuation states over wide frequency bands,” Fairview said. The company said this performance is widely used in transceiver RF and IF sections and in equipment applications such as signal generators to adjust the output level of test signals.

The programmable attenuators from Fairview Microwave have integrated TTL driver logic control bit circuitry that ranges from 5 to 10 binary bits depending on the model. Fairview said that this number of bits benefits in very precise and linear digital control of attenuation step sizes that can be as low as 0.03 dB to 1 dB maximum over the entire attenuation range. The command control interface is via a 15 pin female Micro-D socket or USB connector. The circuits are enclosed in environmentally sealed metal packages with epoxy paint finish with either stainless steel SMA or 2.92mm connectors. Guaranteed operating performance covers a temperature range of -50°C to +85°C.

& Fairview’s new digitally controlled programmable attenuators are in-stock and available to ship today.

ALLEN, TEXAS—Fairview Microwave has introduced a new line of ultra-miniature UMCX, WMCX and HMCX32 cable assemblies. Able to operate from DC to 6 GHz these micro-coax jumpers can be used with wireless communications systems and other wireless applications, including antennas, Wi-Fi, wireless LAN, Bluetooth, LTE and more.

The UMCX and WMCX cable assemblies are compatible with Hirose U.FL and W.FL connectors and feature miniature snap-on connectors with mated connection heights from 1.2 to 2.5mm. Fairview is releasing 40 unique configurations with multiple coax options including 0.81mm, 1.13mm, 1.37mm, RG178 and double shielded RG178. In-series and between-series cable assemblies are available.

All three of the ultra-miniature cables are offered in 6, 9 or 12 inches. Custom lengths are available upon request.

The UMCX, WMCX and HMCX32 cable assemblies are currently available for shipping.

ALLEN, TEXAS—Fairview Microwave has introduced its new series of waveguide directional couplers, featuring 28 individual models. The family of couplers covers a frequency range from 18 GHz to 110 GHz in seven frequency bands, K, Ka, Q, U, V, E and W.

Available in sizes from WR-42 to WR-10, Fairview’s directional couplers are offered with 10 dB or 20 dB coupling values and have high directivity of 30 dB typical with insertion loss as low as 0.6 dB in certain models. The waveguide couplers are available in both standard and split block configurations as well as E-Bend and H-Bend designs. The couplers also feature a multi-hole design for power reflection measurements.

Fairview’s waveguide directional couplers are now in-stock and available for shipping. Fairview Microwave is a supplier of on-demand RF and microwave products.
