Varactor Tuned Navigation Band Preselector: TF0112

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.

Switched Filter Banks

Switched Filter Banks

API Technologies Switched Filter Bank designs draw from a multi-disciplined staff with many years of experience in both microwave filters and control components. By combining filter and switch design expertise, API can provide integrated switched filter assemblies that not only reduce the overall mechanical footprint, but also offer improved electrical performance. This improved performance is achieved by having the ability to align the filters to the switches, thus removing any of the associated mismatches between the two.

7-Way Switched Filter: SA0068-7

7-Way Switched Filter: SA0068-7

MtronPTI’s SA0068 7-way Switched Filter Bank provides transmitter harmonic management with at least 30 dB of 2nd 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.

Bandpass Filter and Band Reject Filter

Bandpass Filter and Band Reject Filter

Planar Monolithics recently rolled out two new filters; the BPF1370-50-CD-TNCMF bandpass filter, and the BRF1370-50-CD-TNCFF band reject filter. Both filters have a center frequency of 1370 MHz, a 2.6” x 1.0” x 0.75” size, and a gray paint finish.

EMI/RFI Filter Sample Kits

EMI/RFI Filter Sample Kits

CTS has recently developed new sample kits of EMI and RFI filters for applications calling for the effective reduction of radio interference in systems where high performance and board space are both critical.

Ceramic/LC GPS Filter

Ceramic/LC GPS Filter

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.

Spiral Filter: JDF-70

Spiral Filter: JDF-70

This spiral filter operates in the 69.5-70.5 MHz frequency range, and has < 12dB insertion loss, <1.0dB ripple, >15dB return loss, and 50 ohms impedance. Download the datasheet for additional specifications.

Coaxial/Tubular Filters: TF Series

Coaxial/Tubular Filters: TF Series

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.
