Fairview Microwave has introduced a family of ultra-miniature UMCX, WMCX and HMCX32 cable assemblies. Commonly used to connect an external antenna to a mini-PCB, these flexible micro-coax jumpers offer operation from DC to 6 GHz and are designed for use in wireless communications systems. Additional wireless applications include antennas for GPS and other radio systems, Wi-Fi, wireless LAN, Bluetooth, ZigBee, LTE, mini-PCI and PDA/PCS/cellular handset applications.
Fairview Microwave’s UMCX and WMCX cable assemblies are compatible with Hirose U.FL and W.FL connectors respectively, and feature miniature snap-on connectors with mated connection heights ranging from only 1.2mm to 2.5mm. In total, Fairview is releasing 40 unique configurations with multiple coax options including 0.81mm, 1.13mm, 1.37mm, RG178 and double shielded RG178 (RG178-DS). In-series and between-series cable assemblies are available. www.fairviewmicrowave.com
Fairview Microwave has released a complete portfolio of coaxial high reliability power amplifiers with broadband frequencies ranging from 0.5 MHz to 20 GHz that can operate over extreme temperatures across -55°C to +85°C. These high-rel amplifiers are commonly used in demanding environments for applications involved with electronic warfare, instrumentation, military communications, radar, point-to-point radio, telecom, test & measurement, medical, and SATCOM industries.
The hi-rel power amplifiers from Fairview are designed to overcome the electrical and mechanical stresses that are seen with exposure to harsh environments. These RF amplifiers boast rugged package enclosures that can withstand vibration and shock exposure during handling and transport. Several models in this offering are designed to meet MIL-STD-202 and MIL-STD-810 environmental test conditions, while some amplifier designs are environmentally screened in production to MIL-STD-202 test conditions. Some models feature integrated heatsink and cooling fans for improved thermal dissipation performance resulting in extended operating life. And for added reliability against harsh environments, certain models utilize hermetically sealed coaxial packages.
Fairview’s power amplifiers can generate saturated output power levels (Psat) up to 100 watts and all models require only a single positive voltage supply ranging from +12 to +42 Vdc. Small signal gain levels range from 11 dB to 58 dB with IP3 linearity up to +66 dBm resulting in high dynamic range. All models are unconditionally stable. www.fairviewmicrowave.com/rf-products/hi-rel-amplifiers.html
Fairview Microwave introduces expanded offerings of low passive intermodulation RF cable assemblies, low PIM adapters and low PIM terminations, commonly used in indoor/outdoor commercial telecom and cellular applications as well as distributed antenna systems (DAS).
Offered in Fairview Microwave’s latest low PIM product expansion are 16 cable assemblies, 20 RF adapters and 2 RF loads. The majority of the cable assemblies are built using formable 0.141 or 0.250 low PIM coax, while assemblies using one-half inch flexible and superflexible low PIM coax are also available. These cables can be ordered with in-series or between-series combinations of Type-N, SMA, 7/16 DIN and 4.1/9.5 mini-DIN connectors. These low PIM cables operate up to 3 GHz or 6 GHz depending on the configuration and exhibit excellent PIM performance of -160 dBc and 1.25:1 VSWR.
Fairview’s lines of low PIM adapters are available in combinations of SMA, TNC, Type-N, 7/16 DIN and 4.1/9.5 mini-DIN coaxial connectors. Many of these RF adapters have PIM performance ranging from -150 dBc to -168 dBc, operating frequencies up to 8 GHz and VSWR of 1.25:1. Also available from Fairview Microwave are two new medium and high power low PIM RF loads. These are available in 50 Watt and 100 Watt versions, both up to 2.7 GHz. The low PIM terminations have PIM ratings of -168 dBc. www.fairviewmicrowave.com
Fairview Microwave has released a line of compact hot-switchable variable attenuators, which are used to reduce the amplitude of an electronic signature in many common electronic scenarios including lab testing equipment, DAS and power and signal monitoring systems.
The attenuators come in 3 and 6 GHz frequency models and several different connector configurations including SMA and N type connectors with side or rear mount positions. Several of these attenuators are hot-switchable, meaning attenuation can be changed on the fly without powering down the system, allowing test data to be read continuously. Several models with varying attenuation adjustments are available including 0 to 12 dB attenuation in 1 dB steps and 0 to 40 dB attenuation in 10 dB steps, with other options available upon request. These new attenuator products also boast low attenuation tolerance and low insertion loss. www.fairviewmicrowave.com
Fairview Microwave has introduced a complete line of mini-DIN 4.1/9.5 adapters intended for use in applications requiring low passive intermodulation (PIM) performance such as cell sites or indoor/outdoor distributed antenna systems (DAS).
Mini-DIN adapters used in RF applications are similar in design to 7/16 DIN connectors, but have a more compact body and offer more precise electrical performance. The 4.1/9.5 mini-DIN adapters offer VSWR performance of 1.25:1 up to 6 GHz. Third-order PIM is less than -160 dBc using 2 tones at 20 Watts. These low-PIM mini-DIN adapters are available in male and female combinations of between-series interfaces for each adapter type including 4.1/9.5 mini-DIN to 7/16 DIN and 4.1/9.5 mini-DIN to Type-N. Two non-low PIM versions are also available.
The 4.1/9.5 adapters are constructed with tri-alloy plated brass bodies and silver plated Beryllium Copper (BeCu) center contacts, allowing low IMD and low attenuation. Additional applications of Fairview’s new lines of 4.1/9.5 adapters include portable sweep testing, telecom installations, wireless infrastructure, OEM in-rack RF routing, in-building systems, and land mobile radio communications. www.fairviewmicrowave.com
