Crane Aerospace & Electronics Microwave Solutions announced the re-launched microwave space qualified products (MSQP) product line. This line offers a range of standard passive products including power dividers, hybrids, couplers and mixers. These products have been previously qualified to internally generated standards derived from industry standards.

SemiGen Inc. has announced that a series of microwave chip capacitors are now available from their RF Supply Center. Series 8000 capacitors offer a working voltage of >50 V and capacitance ranges from 2.0 pF to 600 pF. Series 8100 capacitors offer a working voltage of >100 V and capacitance ranges from 0.1 pF to 399 pF.

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.

Weinschel offers a comprehensive product line of power splitters and power dividers. 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.

Reactel part number 5LM-X1582-T11 filter passes 1164 to 1582 MHz while holding attenuation of greater than 20 dB in the Iridium band of 1616 to 1626.5 MHz.  This unit can be fitted with most any RF connector of your choosing.

Reactel part number 4R9-2000-X4S11 is an ultra-narrowband notch filter which utilizes a unique design to achieve a bandwidth of less than 0.8 percent. Attenuation at the center of the notch approaches 90 dB while insertion loss in the passband is less than 0.75 dB.

Reactel part number 6CX9-1621.25-X10.5T11 is a cavity bandpass filter for the Iridium band. This unit is specifically designed with a narrow bandwidth and high rejection to isolate Iridium frequencies from outside interference due to Inmarsat systems. This unit can be outfitted with any RF connector you may desire.

Reactel part number 16CX11-752-X108N11 is another member of the growing family of 700 MHz LTE units. This particular unit is suitable for the entire 700 MHz band and is centered at 752 MHz and features low loss and high out of band attenuation.

Reactel part number 10CX9-881-X88N11-R is specifically designed for ETCS Systems.  Utilizing a specially designed bandpass circuit, this unit is the perfect fit for ETCS systems.  We have designed a number of variants of these units with differing attenuation specifications, sizes and connectors.

Reactel manufactures filters specifically designed for PTC Systems.  Utilizing specially designed bandpass filters, these units are the perfect fit for PTC systems.  We have designed a number of variants of these units with differing attenuation specifications, sizes and connectors.
