rfsims — Thu, 31 Dec 2020 12:12:10 +0000

This component is a 1030MHz/1090MHz diplexer, i.e. splits incoming signals from a common port into two channels, dependent on frequency (1030MHz or 1090MHz). Each 1030Mhz/1090Mhz channel consists of a cavity filter of fourth order.

Narrowband Filter 20MHz Bandwidth at 1090MHz – HFSS Design

admin — Mon, 14 Dec 2020 07:21:02 +0000

This item includes two designs of a narrowband filter with 20MHz bandwidth at 1090MHz in ANSYS HFSS. The inputs are 50Ω SMA connectors. The order of the filters is four.

The design 02 has a transmission zero at 1090MHz. The details of the simulation results are available in the attached pdf file.

These filters can be used in Identification Friend or Foe (IFF) or Secondary Surveillance Radar (SSR) systems.

Narrowband Filter 20MHz Bandwidth at 1030MHz – HFSS Design

admin — Sat, 05 Dec 2020 05:35:04 +0000

This item is a design of narrowband filter with 20MHz bandwidth at 1030MHz in ANSYS HFSS. The inputs are 50Ω SMA connectors. The order of the filter is four and its return loss is less than -15dB within 1022MHz to 1038MHz.

This filter can be used in Identification Friend or Foe (IFF) or Secondary Surveillance Radar (SSR) systems.
