PDI’s lumped component filters cover the 0.5 MHz to 3500 MHz frequency range. They’re ideal for applications involving radar, airborne vehicle systems, satellite systems, radio receivers, and down-hole systems.
In addition to their standard line of switched filter banks, API technologies recently unveiled a new line with customer-specified frequency coverage from 2 to 7 channels. They cover the 20 MHz to 7500 MHz frequency range with ultimate rejection up to 20 GHz. Low insertion loss and high isolation are achieved through mechanically channelized PIN diode switch manifolds, and lumped element filters have been integrated for increased rejection.
Phonon has been producing an extensive legacy of space-qualified SAW devices since 1987. All products are built to each customer’s individual requirements. Products can be built for either commercial or military space applications. Our space-qualified products are all built to MIL-PRF-38534 Class K reliability.
The TF series of coaxial/tubular filters by PDI cover the 10MHz to 18GHz frequency range. They’re available in bandpass and lowpass configurations and are ideal for ground-based radar, MRI and NMR systems, airborne and satellite (limited) applications, antenna masts, and other high-power applications.
The compact Narrow-Band Notch Ceramic Based Filters feature a frequency range from 500 MHz to 3.0 GHz, and are custom designed to achieve notch specification requirement. These ceramic based filters are now available with higher Q materials, superior depth, and tape and reel packaging.
This wireless communications bandpass filter eliminates Advanced Wireless Service (AWS) interference at Electronic News Gathering-Receive Only (ENG-RO) BAS channel A7 for base stations and towers for television, mobile news gathering, and broadcast wireless services. It mitigates interference of cellular frequencies above 2110.6 MHz.
This is a low pass filter for the record books. With the connectors, it measures over 19 “in length. The pass band is 50MHz to 1990 MHz with less than 1dB of pass band insertion loss. It took over 39 poles to meet the rejection requirements of greater than or equal to 80dB at 2140MHz to 3600MHz.
The new line of YIG Tuned Band-Reject Filters is powered by new patent-pending technologies that are closer to achieving the ‘perfect notch’ in band-reject filters than ever before. This new product line offers major performance advantages including increased minimum rejection bandwidths and notch depth at lower frequencies, a reduction in the maximum 3dB bandwidth at higher frequencies, and a reduction in spurious responses across the board.
