AWS/BAS Co-Site Interference Mitigation Filter: CMF905

AWS/BAS Co-Site Interference Mitigation Filter: CMF905

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.

Cavity Filter: JDCCF014U004

Cavity Filter: JDCCF014U004

This cavity filter operates in the 1150-1650 MHz frequency range, has an insertion loss of <0.3dB, <1.5:1 VSWR, and a DC-900MHz@>40dB; 1800-3000MHz@>40dB rejection. Additional features include female-SMA connection and 50ohms impedance. Download the datasheet for additional specifications.

Combline Cavity Filter for Link 16 Communications: Model 8906

Combline Cavity Filter for Link 16 Communications: Model 8906

This combline cavity filter covers the 962 to 1213 MHz frequency range and features broadband rejection, high power handling, tight cutoff, and a hermetically sealed, compact design. It’s been specifically designed for use in JTIDS, MIDS, and MIDS-J Link 16 communications applications.

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.
