Test & Measurement

Test & Measurement Oscilloscope Probes for High-Voltage Signal Measurements provides the voltage and bandwidth engineers need for making high-voltage measurements referenced to the ground with low input loading. The probe provides 500- MHz bandwidth when used in conjunction with a spring ground tip to reduce inductive ground loading. ■ Keysight www.keysight.com Keysight Technologies, Inc. introduced 200-, 300- and 500-MHz, high-voltage probing solutions with a wider input range, higher common-mode rejection ratio and optimized accessories. The probes are ideal for testing today’s switching power supplies or power devices and for measuring motor drives and vehicle buses. The Keysight N2804A differential probe offers up to 300 MHz bandwidth and ±300 Vdc + peak AC of the maximum differential input range, allowing engineers to use it for a broad range of power applications. Modules DC-10 GHz 1 W Amplifier Module from P1dB RFMW, Ltd. announces design and sales support for P1dB’s P1-AMP00010-1- SMA, a DC to 10 GHz, 1 Watt, amplifier module. The P1-AMP00010-1-SMA is commonly used as a general purpose, broadband amplifier in test and measurement applications but also finds use in system integration projects where flat gain over broad bandwidth are needed. Gain flatness for the P1-AMP00010- 1-SMA is 1.0 dB from DC to 10 GHz. Typical saturated output power is 30.5 dBm at 10 GHz. This SMA connectored amplifier draws only 300 mA from a +8 to +14.5 volt supply. P1dB offers the P1-AMP00010-1-SMA in a small, The N2805A 200-MHz differential probe comes with a 5 m input cable, which allows engineers to easily reach DUTs over long distances. The probes have a differential input resistance of 4 MOhm and low input capacitance of 4 pF to minimize circuit loading. The N2804A and N2805A probes are compatible with Keysight oscilloscopes with a 50-Ohms-AutoProbe interface, which automatically configures the scope for the probe. The Keysight 10076C 100:1 passive probe with 66.7-MΩ input resistance 1.5x1.0“ housing ideal for commercial and industrial applications.. P1dB Stocking Distributor RFMW, Ltd. info@rfmw.com www.rfmw.com AWT Global introduces new Multi-Band PIM Analyzers with S-Parameter Capability AWT Global has launched a new product line of Passive Intermodulation (PIM) Analyzers for manufacturing, R&D and QA: PEM42A Series. These new PIM analyzers can handle up to four frequency bands in the range of 385 MHz to 2600 MHz. Furthermore, it performs S-Parameter measurements without the need to reconnect cables to the device under test (DUT). PEM42A systems consist of a control and switching unit, up to 4 frequency modules and an integrated Agilent 5072A ENA. The ENA serves as precision measurement receiver and for S-Parameter measurements. The control and switch unit now automatically takes care of connecting the right frequency to the DUT. PEM42A feature adjustable RF signal power that ranges from 20 dBm to 44 dBm (higher power levels are available on request). With a noise floor of

RF & Wireless Products Cable Assemblies from DC to 50 GHz from Intelliconnect designs which are undertaken without NRE charges to their customers. Intelliconnect also manufacture a large range of coaxial adaptors to facilitate interseries connection and gender change etc. Typical applications include MIL and aerospace, marine, oil and gas, medical and general microwave markets. ■ Intelliconnect www.intelliconnect.co.uk Intelliconnect (Europe) Ltd, the UK based specialist manufacturer of RF connectors, continues to expand their cable assembly service. Having seen considerable business growth since its launch 18 months ago the operation is relocating to a new facility in Corby and investing in additional production equipment. Intelliconnect provides high quality, UK manufactured, bespoke cable assemblies for both highvolume or specialist small batch requirements for typically RF applications including, medical, test and measurement and defence. Using their own UK manufactured high quality RF connectors, all types of cable assemblies are undertaken from wiring loom assemblies to high performance low loss cables operating up to 50 GHz. Coaxial, triaxial and multi-way connectors may be specified and fully immersible waterproof versions are available. All Intelliconnect cable assemblies are 100% electrically tested before despatch. In addition phase matching is available where required to ensure signal integrity in individual, or batches of, assemblies. In addition to custom cable assemblies Intelliconnect (Europe) Ltd manufactures a wide range of standard and custom RF connectors and components, including waterproof and fast turnaround custom New 15 W GaN on SiC Pulsed Power Transistor M/A-COM Technology Solutions Inc. (“MACOM”), announced a new GaN on SiC HEMT Pulsed Power Transistor for civilian and military radar pulsed applications. The MAGX-000035-015000 and MAGX-000035-01500S are gold-metalized unmatched GaN on Silicon Carbide RF power transistors optimized for a variety of RF power amplifier applications. The devices provide a typical 17 W of peak output power with 15.5 dB of power gain and 63% efficiency. These high performance transistors are assembled using state of the art wafer fabrication processes and provide high gain, efficiency, bandwidth, and ruggedness over multiple octave bandwidths for today’s demanding application needs. Operating between the DC - 3.5 GHz frequency range, the devices are highly robust transistors with high voltage breakdowns and boast a mean time to failure (MTTF) of 600 years. The product is offered in both an enhanced flanged (Cu/W) and flangeless (Cu) ceramic package which provide excellent thermal performance. Samples of MAGX- 000035-015000 and MAGX- 000035-01500S are available from stock. Final datasheets and additional product information can be obtained from the MACOM website. ■ MACOM www.macom.com Proprietary Solutions Enhance LTE Data Throughput Skyworks Solutions, Inc. announced that a family of groundbreaking diversity receive modules (DRx) for LTE smartphones is currently ramping with several tier-one manufacturers. This new product category leverages Skyworks’ systems level expertise and techniques developed for cellular base stations to create a highly innovative solution integrating multiple low loss RF switches, receive SAW filters and LNAs to dramatically enhance downlink data rates in LTE advanced MIMO systems. By amplifying the receive signal without increasing noise, receiver sensitivity is improved depending upon the band. As a result, carriers benefit from improved network efficiency while consumers enjoy considerably faster download speeds. Approximately 75 percent of network traffic on mobile devices is on the downlink or receive side. Skyworks’ highly integrated DRx modules maximize data throughput, minimize complexity and reduce overall footprint, thereby helping mobile communication networks deliver increasing amounts of data. ■ Skyworks www.skyworksinc.com hf-praxis 1/2015 39
