Using a SAW or ceramic bandpass filter and a low noise amplifier (LNA), it stops out-of-band intermodulation while providing additional gain for increased sensitivity. The LNA is before the SAW filter. This particular model is tuned for use with ADS-B frequencies (1090Mhz).\u003c\/p\u003e\n\u003cp\u003eThe LNA used is a MiniCircuits PSA4-5043+ which provides at least 16dB of gain @ 1090Mhz. To stop out-of-band intermodulation, a 1090Mhz SAW bandpass filter is fitted. The insertion loss of this filter is approximately 2.3dB, which does increase the overall noise figure of the unit to 0.75dB, which means the overall gain of the unit is at least 14dB. Connectors are SMA female on both sides.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1090MHz ADS-B Filtered Preamplifier\u003c\/li\u003e\n\u003cli\u003eConnectors SMA Female (Both Sides)\u003c\/li\u003e\n\u003cli\u003eGain: Min 14dB\u003c\/li\u003e\n\u003cli\u003eNF 0.75dB\u003c\/li\u003e\n\u003cli\u003eSupply Voltage: 5V\u003c\/li\u003e\n\u003cli\u003eCurrent Draw: 56mA approx.\u003c\/li\u003e\n\u003cli\u003eSupplied Assembled in Metal Case\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMini-B USB Connection\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eNO power LED\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eDimensions: 63.5mm x 63.5mm x 30mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cp\u003eThe following resources are from the latest version, but specs and internal hardware are mostly the same.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/store.uputronics.com\/files\/HAB-FPA_Datasheet_Latest.pdf\"\u003eDatasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/store.uputronics.com\/files\/LNAMechcanicalDiagramV2.pdf\"\u003eMechanical Diagram\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Uputronics","offers":[{"title":"Default Title","offer_id":50847362515217,"sku":"106000","price":34.56,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6285\/6209\/files\/ads-b-1090mhz-filtered-preamplifier-mini-b-version-uputronics-106000-42262484287683.jpg?v=1735211586","url":"https:\/\/abcd3032.myshopify.com\/hi\/products\/ads-b-1090mhz-filtered-preamplifier-mini-b-version","provider":"Tayyab Zak","version":"1.0","type":"link"}
