Reactel model 3TP-1176.45/1575.42-S11 is a cavity triplexer designed for all three GPS frequencies: L1 (New Civilian) L2 (Civilian) and L5 (Safety of Life). The passbands for this particular unit are L1: 1560.42 to 1590.42 MHz; L2: 1212.6 to 1242.6 MHz; and L5: 1164.45 to 1188.45 MHz. This unit has insertion loss of less than 1 dB mid-band, and a high degree of band to band isolation. It is outfitted with SMA connectors and is sized at 1.625" × 2.5" × 4.75" excluding connectors. Reactel manufactures a wide variety of GPS filters and multiplexers and dual filters; please contact the factory with your requirement.
3D EM Simulation Software
XFdtd 7 (XF7) is the market’s most modern 3D electromagnetic (EM) simulation software for FDTD-based modeling and simulation. XF7 simplifies workflow with a streamlined user interface, cross-platform functionality, and several unique time-saving features. XF7 includes XStream, Remcom’s GPU acceleration technology, for free. Using the power and flexibility of NVIDIA’s CUDA architecture, XStream improves EM simulation performance with ultra-fast FDTD numerical computations -- from 30 to 300 times faster than a modern 64-bit CPU.

Leadless SMT Ceramic Packages
Remtec extended its line of cost-effective, low upfront tooling, ceramic leadless substrates and packages to mm-wave. Etchable, high definition conductors (± 5 µ), low RF loss thermal hermetic vias and copper heat spreaders eliminate the need for an external metal housing, providing shorter low-inductance interconnects. Miniature size packages (hermetic if needed) are fabricated using PCTF technology, with integrated resistors, transmission lines, and multilayers and improved electrical and thermal performance. Remtec offers microwave modeling, design, test and assembly of MW packages.
GaN Power Amplifier
RFHIC introduced a molded styled power amplifier (GaN on SiC) generating 20 W and covering 20 to 1000 MHz. RWS05020-10 is based on GaN on SiC transistor, promising a solid reliability at high temperature; it provides a 36 dB of gain and a typical 43 dBm at P3dB with 50 percent efficiency. Moreover, the physical size of RWS05020-10 is only 2.1" × 1" × 0.5", which is much smaller than a typical business card.

GaN Wideband Power Amplifier
RFMD’s RF3826 is a wideband power amplifier designed for CW and pulsed applications such as wireless infrastructure, radar, two-way radios and general-purpose amplification. Using an advanced high power density RFMD fabricated Gallium Nitride (GaN) semiconductor process, these high performance amplifiers achieve high efficiency, flat gain and large instantaneous bandwidth in a single amplifier design. The RF3826 is an input matched GaN transistor packaged in an air cavity ceramic package.
Test grade cables are desired in applications where multiple connector attachment and continuous flexing demands are a priority. RF Industries now offers 18 GHz precision test cables in standard or custom lengths, suitable for production or lab environments. Featuring high-grade, passivated, stainless steel SMA males with PTFE insulators, this unique cable is configured for low loss and low VSWR. With triple shielding for optimum EMI protection, they are very phase-stable during mechanical and environmental stresses. Manufactured to MIL-DTL-17, type IX specification.

High Frequency Laminates
Rogers recently launched the groundbreaking RO4360 high frequency laminates, the latest addition to the RO4000® product family. RO4360 thermoset laminate materials are specially formulated to meet a Dk of 6.15 and exhibit a low dissipation factor of 0.0038 at 10 GHz. RO4360 laminates possess a Z-axis coefficient of thermal expansion of 30 ppm/°C (CTE) for dependable plated-through-hole (PTH) quality in multilayer circuit and package designs and are lead free process capable. Look for Rogers bonding layer with a matching 6.15 dielectric constant coming soon.
RF Cable Clamp
Rosenberger introduces a Micro RF Cable Clamp whose ultra small size and excellent performance from DC to 8 GHz makes it the designers’ choice for high density applications. The mating cable connector is spring loaded; just push in place, wait for the click and the connector is locked in the correctly aligned position. The Micro RF Cable Clamp fits on pc board space of 5.0 × 3.6 mm and is < 2 mm in height, a perfect connector for premium space applications. The mating cable connector comes in a variety of configurations, including Cable Clamp to SMA, Cable Clamp to SMP and Cable Clamp to Cable Clamp.
Rosenberger of North America LLC
San-tron has announced the release of a new series of 2.92 mm connectors. S292™ connectors have been standardized to Thunderline-Z’s TL-150 glass bead resulting in a transitional RF geometry that greatly reduces the tolerance sensitivity of the final product deployment. By matching the dielectric properties of Corning glass #7070 within the 50 ohm structure of a 0.012 diameter pin, the company achieves VSWR of < 1.04 through 12 GHz and < 1.18 through 40 GHz.
FDTD Simulation Platform
Named after one of the most impressive mountains in Switzerland, the FDTD simulation platform SEMCAD-X offers extended usability (novel window management approach), functionality (handling, visualization) and features (network distributed optimization, multiport analysis, multi-threaded postprocessing). SEMCAD-X is defining new standards to solve real RF and MW engineering problems.
