Ceramic Chip Inductors
AVX Corp. released a new series of ultra-miniature multilayer ceramic chip inductors for high frequency RF applications. The new LCCI Series inductors are currently available in three standard EIA chip sizes—0201, 0402 and 0603— with tight-tolerance physical dimensions almost exclusively in the submillimeter range and tin-plated surface-mount terminations, enabling compatibility with high density PCBs and reflow soldering in space- and weight-constrained applications within the telecommunications and networking markets, as well as with lead-free and RoHS directives.

Programmable Attenuator
The new 50P-2101 programmable attenuator from JFW has an increased attenuation range of 0 to 63.5 dB with the precision of 0.5 dB steps. It operates from 100 MHz to 18 GHz and is guaranteed monotonic across the entire band. +5 V DC supply and TTL logic control allow for easy integration into any communications, EW, satcom or radar RF test system. Switching speed is 1 microsecond maximum and SMA female connectors are standard.

Attenuator Programs
Mini-Circuits’ model RCDAT-50G-30 is a programmable attenuator with an attenuation range of 0 to 31.5 dB in 0.5 dB steps from 100 MHz to 50 GHz. It can be controlled via USB or Ethernet connection, with a single interconnection enabling independent control of multiple attenuators in a master/slave configuration. Typical insertion loss at 0 dB attenuation is 3.25 dB from 100 MHz to 15 GHz, 6.0 dB from 15 to 35 GHz and 8.0 dB from 35 to 50 GHz, while typical full-band VSWR is 1.50:1 or better from 25 to 50 GHz. Ideal for measurement and communications systems, the RoHS-compliant attenuator features typical transition time of 100 ns.

Ultra-Wide Bandpass Filters
RLC Electronics is manufacturing ultra-wide bandpass filters to help customers pass broadband filtering requirements with over 70 percent bandwidths (up to 160 percent). These multi-octave filters are available from low frequency up to 40 GHz. The unit pictured above is an 18 to 40 GHz bandpass filter, with low loss (0.8 dB maximum), sharp rejection (45 dB at 10 GHz and 48 GHz) and a small footprint (1.2” plus connectors). Other custom options are available depending on customer requirements, including high-power ultra-wide bandpass filters.
