Ground Systems • UAV • Tactical Airborne • Airborne Command • Space K&L Microwave K&L has developed a series of reduced-size lowpass clean-up filters with cut-off frequencies as low as 460 kHz handling up to 3.0 kW CW. Several innovations minimize dissipated power. Part 3LL10-0.46/XQ0.70- N/N, measuring 12.3”L x 3.5”W x 2.1”H, features 0.5 dB insertion loss DC to 460 kHz and 60 dB rejection at 700 kHz, handling 3 kW input power. A 4.5”L x 1.9”W x 1.25”H package passes to 100 MHz, rejects at 140 MHz, and handles 1.1 kW CW power. www.KLMICROWAVE.com BSC BSC has independently developed a fully reconfigurable adaptive filter bank solution, designed for fast and seamless switching to any of 256 filter states across the 2-18 GHz range. The BSC design facilitates a step change in EW front-end preselection (or protection), adding complete flexibility by producing any combination of bandpass and band-stop states almost instantly (<100 ns). Suitable for fast-jet, naval and ground-based environments, the robust customized architecture is not limited to the 2–18 GHz range or equal channel widths. More specific solutions may be offered at VHF/UHF or X-Band. Dow-Key® Microwave Dow-Key® has over 70 years of expertise in designing and manufacturing RF switches and specializes in custom and rugged switching products for mission-critical applications. Latest innovations include an L-Band, non-blocking fan-out/ fan-in solid state network for a mobile SATCOM station. The custom system is a dual 4x48/48x4 switch matrix in a ruggedized chassis with sub-modules providing exceptional RF performance. The design features a minimum of 60 dB isolation and a noise figure of 18 dB/20 dB. The control module is equipped with a Windows-based PC and removable and replaceable duplex power supply cartridges. The system may be controlled via LCD touchscreen and Ethernet with SNMP v1 protocol. www.DOWKEY.com Pole/Zero Pole/Zero introduces new voltage-tuned filters (VTF) with center frequency ranges extending up to 20 GHz for EW and Radar applications. The VTFs meet extremely fast tuning requirements of under 150 ns with high selectivity, low loss and power handling up to +10 dBm in bandpass and notch configurations. These Rx-oriented filters complement Pole/Zero’s existing high power Tx tunable bandpass and notch offerings for EW environments.
