NEW PRODUCTS & SERVICES COMPONENTS / SUBSYSTEMS Fairview Microwave Releases Ruggedized VNA Test Cables with Phase Stability Fairview Microwave, Inc. has released a family of ruggedized VNA test cables operating up to 40 GHz. These new amplitude and phase stable ruggedized VNA test cables provide the reliable and repeatable, accurate test results that users require. Fairview's newest lines of VNA test cables boast a maximum phase change of +/- 2°at 18 GHz, +/- 3° at 26.5 GHz and +/- 5° at 40 GHz. This minimal phase change is essential because amplitude and phase variation following VNA calibration can cause inaccurate S Parameter measurements. To mitigate these inaccuracies, amplitude and phase stable cables are required to ensure precise Vector Network Analyzer measurements. The phase stable cables from Fairview can be ordered with male or female versions of SMA or Type-N connectors for cables operating to 18 GHz, 2.92 mm and 3.5 mm connectors for cables operating to 26.5 GHz or 2.4 mm and 2.92 mm connectors for test cables performing up to 40 GHz. These cables are equipped with torsion-resistant connector heads that are attached directly to a stainless steel conduit style armoring providing a rugged design for up to 5,000 mating cycles with proper care. This armoring also enhances amplitude and phase stability by preventing undue stress from over bending, while also maintaining the flexibility required for testing in a lab environment. Amphenol RF Offers 4.3/10 Connector Series with Low PIM Performance Amphenol RF is pleased to offer a full range of 4.3-10 connectors and adapters, which are engineered for the wireless market and are well suited for applications requiring low passive intermodulation, or PIM. The 4.3-10 connectors offer the same, robust design as 7/16 connectors but are smaller and up to 40 percent lighter, allowing for much more dense, lighter weight applications. These designs are IP-67 compliant to protect against dust and water ingress for outdoor applications, and provide excellent VSWR performance up to 6.0 GHz. Separate electrical and mechanical components yield very stable PIM performance regardless of coupling torque, allowing for easier installation. Silver plated contacts and White Bronze plated bodies offer a high-degree of conductivity, corrosion resistance and durability. Pasternack Announces Line of High-Rel Frequency Dividers Pasternack has announced an all new line of high-rel frequency dividers that cover wide frequency bandwidths from 0.5 to 18 GHz and are available in 2, 4, 5, 8 and 10 divide-by-prescaler configurations. These modules are well suited for use in common phase locked loop and frequency synthesizer circuit designs that may involve applications for aerospace and defense, satellite communications, VSAT, test and measurement equipment, and point-to-point radios. The new frequency dividers from Pasternack utilize advanced GaAs HBT MMIC semiconductor technology that produces low additive single sideband (SSB) phase noise performance with typical levels down to -155 dBc/Hz at 100 KHz offset. Input power ranges from -20 to +10 dBm with output power ranging from -1 to -4 dBm depending on the model. Additional performance includes a fast output transition time of 100 picoseconds, high reverse leakage levels up to 85 dB, single +5V DC power supply, and an operating temperature range of -55°C to 85°C. All models are EAR99. These frequency dividers are designed into compact miniature packages that support field replaceable SMA connectors and mounting fixtures that can be removed for convenient PCB "drop-in" applications. The rugged Kovar package designs are gold-overnickel plated and hermetically sealed and guaranteed to meet MIL-STD-883 environmental test conditions for temperature cycle and fine & gross leak testing. 22 Antenna Systems & Technology Fall 2016 www.AntennasOnline.com http://www.AntennasOnline.com
