Integrated Microwave Corp. offers the 928103, a 914.5 MHz ISM bandpass filter. This filter is designed to reject interference to and from adjacent radio services, like the cellular radio band. This high-Q ceramic filter is designed using eight resonators that exhibit high Q (over 1000). The result is a compact filter that handles over 10 W CW, and has low insertion loss (5 dB max) considering its bandwidth.
Aeroflex/Weinschel offers a comprehensive product line of power dividers and power splitters. Many of these standard products were designed for particularly demanding broadband requirements, SWR, and high power system applications. They have a wide selection of connector types and offer frequency express shipment on select models.
Linear Technology Corporation announces the LT3048, a step-up DC/DC converter with an integrated LDO output that delivers a low noise, low ripple 15 V bias supply. The LT3048-15 delivers up to 40 mA of continuous output current at 15 V with output ripple and noise less than 500 µVPK-PK and 0.1 % load regulation. The device operates from an input voltage range of 2.7 to 4.8 V, making it suitable for single-cell Li-Ion batteries or 3.3 V logic rails.
Linear Technology Corp. announces the LT8309, a flyback secondary-side synchronous rectifier driver that replaces the output diode with a MOSFET, allowing up to 10A output current without the use of a heat sink. The maximum output current of a flyback power supply has been limited by the power loss and heat generated from the output diode when no heat sink is used.
Agilent Technologies Inc. introduced the 33600A Series waveform generators with exclusive Trueform signal-generation technology. With Trueform, the instruments are able to deliver unmatched capabilities used to generate a full range of signals. The 33600A Series comprises four different one- and two-channel models and can generate waveforms up to 120 MHz at a 1 GSa/s sampling rate.
RFMW Ltd. announces application and sales support for a new line of low PIM (Passive Intermodulation) coaxial switches from Radiall, a global leader in design, development and manufacturing of innovative interconnect solutions. Radiall developed a broad series of switches including the following configurations: SPDT, DPDT, SP4T, and SP6T. These configurations are available with either SMA (up to 18 GHz) or N (up to 12.4 GHz) type connectors.
Anritsu Co. introduces an internal atomic clock option for its MS2720T Spectrum Master handheld spectrum analyzer that allows users to acquire excellent frequency accuracy, including in environments in which the GPS cannot be used. Integrating the atomic clock inside the MS2720T provides field engineers and technicians with a durable, handheld spectrum analyzer that can deliver the extremely high accuracy necessary to prove regulatory compliance.
Skyworks Solutions Inc., an innovator of high performance analog semiconductors enabling a broad range of end markets, unveiled a set of antenna switch solutions supporting LTE, LTE-Advanced and next-generation carrier aggregation architectures. The portfolio includes highly integrated antenna switch modules (ASM) as well as transmit and receive diversity switches. The dual-mode MIPI® RFFE-compliant modules are modem agnostic, making them compatible with every leading chipset provider.
Linear Technology announces the LTC3107, a highly integrated DC/DC converter designed to extend the life of a primary battery in low power wireless system networks (WSNs). The LTC3107 combines energy harvesting and power management capability with a primary battery cell to extend the battery’s usable lifetime. The LTC3107 harvests energy from thermoelectric generators (TEGs) and thermopiles when these sources are available.
TEGAM Inc., a leading supplier of innovative RF power measurements, was recently awarded Patent No. 8,610,069, “Coaxial to Dual Co-Planar Waveguide Launcher for Microwave Bolometry,” This patent describes a new way to construct bolometers—a type of microwave power sensor that uses thermistors—that makes them more accurate and easier to assembly.
