Filters

The 312 Series of pre-filtered GPS LNAs (low noise amplifiers) features a low noise figure, a wide input voltage range, compliance with many MIL-STD-810 and MIL-STD-461 requirements, and more. The LNAs come in a small, lightweight hermetically sealed package.

MtronPTI’s SA0068 7-way Switched Filter Bank provides transmitter harmonic management with at least 30 dB of 2^nd harmonic rejection in seven selectable frequency bands from 30 MHz to 512 MHz. With a low insertion loss of less than 1.3 dB, 30 Watts of power handling and a small, 65 mA current drain max, the SA0068 is ideal for applications such as multiband tactical radios and portable radio power amplifiers.

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.

BoCen Microwave designs and produces a complete line of waveguide filters, duplexers, and multiplexers that cover the 2-50 GHz frequency range. They’re ideal for radio and defense communications applications and are available in W/G flange or connectorized configurations.

DLI’s 2-18 GHz bandpass filters are ideal for use in applications involving the C, X, and Ku bands, satellite communications, satellite TV, weather and radar, and military communications. They feature frequency stability over temperature, full shielding, and a compact sizes across the entire line.

MtronPTI’s TF0112 varactor tuned aviation navigation band preselector improves safety in cross country and landing operations by attenuating interfering signals that might cause a cockpit radio to lose lock on a desired VOR or localizer/glide-slope signal.

API Technologies (Utilizing the combined heritage of CMT, Spectrum Microwave, Salisbury Engineering, and FSY Microwave) has developed and produced high quality, High “Q” Filters since 1983, and assisted major wireless carriers and installers with co-location solutions at BTS sites. Key performance features include Low PIM (passive intermodulation), high isolation and low insertion loss.

The 8LBCRLC-150/1575/20-O is a hybrid ceramic/LC GPS filter with a DC bypass and lightning protection. It has a center frequency of 1575+2 MHz, <1 dB insertion loss, <200 mA current, <4.5 dB insertion loss, <1.5:1 in/out VSWR, 3 dB bandwidth at 25-30 MHz, and more.
