SPINNER’s low PIM attenuator reduces cost by ensuring much more flexibility during installation processes. The low PIM attenuator can be adjusted between 15 and 30 dB and performs with -160 dBc/-165 dBc in mobile carrier frequencies. First DAS outdoor installations have proven to save up to 90% of time during power adjustment. Site and in-building installations will be much faster and more efficient due to the flexibility provided by SPINNER’s low PIM attenuator.
Rogers RO4835 high frequency laminates, specially formulated with improved oxidation resistance, were developed for applications needing improved stability over time and temperature, while maintaining the cost advantages of a thermoset, FR-4 processable material. RO4360G2 laminates have a tailored high Dk of 6.15 at 10 GHz, which allows next generation power amplifier designers to meet size and cost reduction targets
MACOM introduced the MAAM-011109-DIE, a wideband amplifier. The MAAM-011109-DIE provides customers with 50 Ohms matching and typical return losses better than 15 dB. Features of the MAAM-011109-DIE include gate bias adjust to change current setting for power or temperature, gain trim control that allows 15 dB of gain control (0 to -1 V) and a temperature-compensated power detector that provides a DC voltage in relation to the output power.
Weinschel's low PIM products offer a rugged construction low profile design free of solder joints that covers DC to 6.5 GHz, with power handling up to 175 W average and IM3 levels as low as -150 dBc output and -120 dBc reflected dependent on dB value. Model 254 is available in 10, 20, 30 and 40 dB. Other features include quality connectors with special high temperature support beads and choice of Type N or SMK (2.92 mm).
DiTom Microwave has released a new Ku Band (13.75-14.80 GHz) space qualified isolator. The DS1011 is manufactured to meet or exceed environmental space-level reliability including thermal shock, sine and random vibration, temperature cycling, and thermal vacuum survivability over a specified qualification and acceptance test plan.
Anritsu Company introduces Web Remote Tools for its Spectrum Master™ MS2720T handheld spectrum analyzer that allows the instruments to be controlled from any web-enabled device, including laptops, tablets, and smart phones, over an Ethernet link. Web Remote Tools test Remote Radio Heads (RRUs) and other inaccessible radio units at 3G and 4G base stations.
The Model 250T6G18 is a self-contained, forced-air-cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where instantaneous bandwidth and high gain are required. A reliable 300 W TWT provides a conservative 250 W minimum at the amplifier output flange. Stated power specifications are at the fundamental frequency.
Richardson RFPD Inc. announced the availability and full design support capabilities for an expanded portfolio of multi-octave, wideband MMIC devicesfrom Microsemi Corporation. The thirty-two additions to the portfolio include additional LNAs and medium-power amplifiers, as well as prescalers, voltage variable attenuators (VVAs), and amplifier modules. The new devices also extend the Microsemi MMIC family maximum operating frequency from 22 GHz to 65 GHz.
Custom MMIC is pleased to announce the addition of the CMD219C4, a new GaN low-noise amplifier. The CMD219C4 is a broadband MMIC low-noise amplifier fabricated in GaN technology that operates from 4 to 8 GHz with a gain of 22.5 dB, a noise figure of 1.0 dB, and an output 1 dB compression point of +17 dBm. In terms of survivability, the CMD219C4 can withstand RF input power levels of up to 5 W without permanent damage.
Richardson RFPD Inc. announced the availability from stock and full design support capabilities for four 1200 V SiC MOSFET-based power modules from Vincotech. The modules are available in two versions. The first is a flow3xPHASE 0 SiC three-phase inverter module with 3x BUCK/BOOST and split output topology. The second version is the flow3xBOOST 0 SiC with three-channel boost circuits.
