The latest version of the RF module, an add-on product available in the COMSOL Multiphysics® software, features an extended part library with edge launch connectors and a new adaptive frequency sweep study type. This study type enables users to compute the frequency response of a linear model more efficiently while using a very fine frequency resolution with the asymptotic waveform evaluation (AWE)—a reduced-order modeling technique.
Exceed Microwave’s WC-Series waveguide diplexers can provide very wide passbands and also comes in small sizes. DPX-WC-22-28-34 is a WR34 diplexer covering nearly the entire waveguide operating frequency band. Each channel bandwidth of DPX-WC-22-28-34 is roughly 20 percent while maintaining very good return loss at all ports. The size is only 1.5 x 1.8 x 0.9 in. which allows waveguide assemblies to be compact. WC-Series diplexers are available in different waveguide sizes. Exceed Microwave designs and manufactures high performance waveguide and coaxial filters.
Fairview Microwave Inc.
PIN Diode Waveguide Switches
Fairview Microwave Inc., a provider of on-demand RF and microwave components, has released a new line of E- and W-Band PIN diode waveguide switches. These single-pole single-throw (SPST) and single pole double-throw (SPDT) mmWave waveguide switches offer an ultra-broadband frequency range with fast switching performance. They are ideal for telecommunications, test instrumentation, research and development programs and radar front-ends in applications that involve general switching, receiver protection, pulse modulation and antenna beam switching.

Electrically Conductive Systems
Master Bond MB600S is a silver conductive water based sodium silicate system for shielding applications that withstands temperatures up to 700°F. MB600S will cure at room temperature in 24 to 48 hours or in 1 to 2 hours at 80°C. It features high temperature resistance with a service temperature range of 0°F to 700°F. The compound is available in glass jars, and has a shelf-life of six months in original, unopened containers at room temperature.
Coaxial RF Surge Protectors with 4.3-10 Connectors
PolyPhaser’s SX series of surge arrestors now includes 4.3-10 connectors. Using PolyPhaser’s patented spiral inductor technology, these arrestors respond almost instantaneously to a lightning surge. Available in DC pass and DC block, all models have a typical PIM rating of -130 dBM and support broad frequency ranges from 698 MHz to 2.7 GHz. The compact, weatherized design makes these arrestors ideal for use with small cells and DAS applications that require 4.3-10 connectors.
RFE’s broadband Synthesizer covering the entire 0.1 to 20 GHz spectrum is reliable, fast tuning and low cost. The design takes advantage of the latest readily available MMIC components, which reduces the parts count and module footprint. It also minimizes the need for hand-tuning. The result is a low-cost, lightweight, fully-integrated module able to perform in the harshest environments. Smallest possible footprint 3 x 3 x 0.7 in., least weight, with < 50 µs tuning speed option.
Reverse Polarity Adapters and Connectors
RF Superstore has expanded their product offering to include a large selection of in-stock reverse polarity adapters and connectors. The newly added products are coaxial adapter designs made of brass with nickel or gold plating and 50 Ohms impedance. The product lines span in-series and between-series BNC, N, MMCX, SMA and TNC.
Spacek Labs’ active frequency quadrupler, Model A487-4XW-19, is a frequency multiplier designed for output operation from 44 to 51 GHz. Requiring only 5 dBm input power, it is capable of generating 20 dBm typical output power across the entire frequency range with better than 35 dBc undesired harmonic rejection. This active quadrupler is ideal for use as a driver for subsequent multiplication used in very high frequency communication systems.
Spectrum Instrumentation GmbH
The new M2p.59xx series of 16-bit PCIe digitizers from Spectrum deliver an unrivalled combination of features, all packed into one very small half-size PCIe card. Furthermore, you can choose exactly the performance level you need by selecting from 20 different models. Units are available with sampling rates of 20, 40, 80 and 125 MS/s, and with 1, 2, 4 or even 8 channels. Spectrum Instrumentation offers a full five year warranty.
2.2-5 Calibration Kit
New applications such as small cells, MIMO and DAS are driving the development of even more compact network equipment and smaller connectors to support the further miniaturization of antennas and RRUs. The new 2.2-5 connector system is derived from 4.3-10 and delivers the same excellent electrical performance while only being half the size. It is now well on its way to being standardized, and SPINNER has already launched the first high-precision calibration kit for it.
The model ASX40-B217 multiplier product, with the output operating frequency range of 18 to 40 GHz. The output frequency range is further complemented with medium output power levels up to +17 dBm minimum across the entire frequency band. This multiplier features output harmonics better than 20 dBc, and is designed with a cost-effective four year warranty program. The ASX series products are offered in many different broadband frequency ranges listed in their recently updated website.
