- Description
- Sources Sought The USGS is conducting market research to determine the availability of qualified businesses capable of providing: Quantity: Eight (8) Brand Name or Equal to 4RF Part Number: APSB-KDUP-135-N0-BR Nomenclature: 4RF+ Acc, kit, Duplexer, 135-175 MHz, N0, BR Description: Aprisa SR+ Duplexer Kit for a SR+ Radio containing:1x 1U 19"" rack front mount shelf with duplexer mounting brackets and screws to mount 1x SR+ radio and 1x duplexer1x N0 Duplexer 135 MHz, s4.6 MHz, p0.5 MHz2x TNC to SMA right angle 640mm cables Shipped to: Seattle, Washington 98195-1310 ////////////////////////////////////////////// As discussed in the salient characteristics this sources sought announcement is not a request for quote or proposal and the Government is not committed to award of a purchase order or contract pursuant to this announcement. The information resulting from this market research is simply for planning purposes to assist the Government in determining its acquisition strategy. The Government will not pay for any costs incurred in the preparation of information for responding to this notice. The North American Industry Classification System (NAICS) code 334290 Other Communications Equipment Manufacturing associated size standard 800 apply to this announcement.

Responses to this announcement shall only be accepted through electronic mail addressed to jberberena@usgs.gov and must be uploaded and received in their entirety no later than December 4, 2023 @0500 PST. Technical Specifications: The USGS requires duplexers that are compatible with existing 4RF radios in use and can be tuned to specific frequencies. 1. The Frequency Range the duplexer must operate within is 134-172Mhz for low side filter and 138- 176MHZ high side filter 2. Bandwidth requirements to ensure compatibility with your system is 25Khz 3. The maximum acceptable insertion loss to improve system efficiency is less than 2.5 DB 4. The required level of isolation between transmit and receive paths to avoid interference is 4.6 MHZ 5. The maximum power level the duplexer must be able to handle is 20W 6. The required impedance is 50 ohms. 7. The acceptable VSWR limit for efficient power transfer. N/A this is filter not an antenna. 8. The type of RF connectors required are N type to antenna and SMA from radio 9. Size is critical due to space limitations, H = one and � inches, W= 13 and 3/8 inches, L=11 and 5/8 inches. 10. The operating temperature range the duplexer must withstand is from -40 F to 158 F. 11. No Mil-specs requirements 12. Must be compatible with 4RF radio 13. This is a frequency filter so it must be retuneable inside the the 138Mhz � 172 Mhz range. 14. No additional certifications required 15. This must have a 2 year warranty as we will be testing for 3 months in house then deploy to remote location for duration.
