HP Series Filters
KYOCERA AVX has released a new series of miniature highpass thin-film filters engineered to provide excellent high frequency performance in a variety of space constrained microwave and RF applications in the telecommunications, automotive, consumer electronics and military markets. The new HP Series highpass thin-film filters are based on proven multilayer integrated thin-film technology that enables the quick adjustment of RF parameters and development of custom filters.
Surface-Mount 90° Hybrid
MIcable released the new 0.5~6 GHz high power surface-mount 90-degree hybrid. It has low insertion loss, low VSWR and 100 W power handling capability with excellent stability and heat dissipation ability in a small package. It is suitable for power amplifier, power combining network, antenna feed network, modulator and phase shifter applications.
Wide Notch Bandwidth – Band Reject Filters
Micro Lambda Wireless Inc. has developed a new yttrium iron garnet based filter that provides superior notch depths over the 6 to 18 GHz and 6 to 20 GHz frequency ranges. This new filter provides a tunable notch of 80 MHz minimum at 40 dBc down. The 3 dB bandwidth is 250 MHz maximum with typical passband insertion loss of 2.2 dB. YIG-based notch filters for EW and ECM.

5 to 2000 MHz, 12 dB Coupler with Low Loss
The MRFCP8752 is a broadband 75 Ω coupler that provides excellent performance for signal level monitoring in DOCSIS 4.0 applications. Utilizing a 12 dB coupling factor, this component provides CATV system designers a low loss < 1.1 dB, flatness of ±0.5 dB and excellent return loss of 22 dB over most of the band. The MRFCP8752 is in a standard surface-mount package (.250 × .280) with standard pinouts for “drop in” performance. Contact MiniRF at 408-228-3533 for additional technical information, pricing and availability. Smaller packaging options may also be offered.
A balun is one of the primary components used in mmTron high speed converter interfaces to transform between differential and single-ended signals. When we surveyed the market for a balun to use, we were not satisfied with the performance, size and physical layout of what we found. So, we designed our own MMIC baluns and have added them to our growing list of products. We think they set new records for bandwidth, insertion loss and amplitude/phase matching.
RF Resistors & Loads
Remtec now offers RF resistors and loads up to 6 GHz to handle power up to 500 W, while maintaining excellent thermal properties. Produced using thick film screen-printed resistors on ceramic substrates — including alumina, aluminum nitride or beryllium oxide — based on customer designs, frequency range, configuration and thermal dissipation goals. Remtec brings 35+ years of cutting-edge thick film processing, screen printing, plating and laser trimming experience to the task and is well-positioned to help bring overseas production (re-onshoring) to the U.S.
24.25–30.5 GHz RF Front-End
Richardson RFPD Inc. announced the availability and full design support capabilities for a new RF front-end module from United Monolithic Semiconductors. The CHC6054-QQA is a high-power front-end (HPFE) incorporating transmit and receive paths and a transmit/receive switch. It operates in the 24.25 to 30.5 GHz frequency range and is designed for telecom radio systems applications. The new HPFE typically exhibits an Rx gain of 18 dB with a low noise figure of 3.2 dB, and a Tx gain of 28 dB with +31 dBm saturated output power.

CABLES & CONNECTORS
Remoting Over Fiber
Antenna remoting over fiber enables greater flexibility to locate an antenna away from a radio head. Coax cables or waveguides have RF losses and are cumbersome to install. RF over fiber enables “virtual cable” installation over flexible, easily deployed fiber. Such an antenna remoting solution was deployed and validated by the US Navy. The Common Data Link (CDL) is a secure communications protocol, established by the U.S. DOD, for transporting signals, intelligence and imagery.
