Design, build and test a two-way frequency shifter board, 5.15-7.15 / 8.15-10.15 GHz

Hello, Please open the attached PDF first. It shows the board. HI-GAIN is a networking and wireless equipment distributor in Beirut, Lebanon, in business since 1990. We need an RF engineer to design, build and test our board until it works. You need your own test equipment that works above 10 GHz; list it in your bid. The board drawings in the PDF are not final. Design it the way you think is best, as long as it meets the points below. What the board does: 1) Transmit: shifts 5.15-7.15 GHz up to 8.15-10.15 GHz. 2) Receive: shifts 8.15-10.15 GHz back down to 5.15-7.15 GHz. 3) One fixed 3 GHz oscillator on the board, used in both directions. 4) Two RF chains, one per polarisation. 5) Input: one SMA per chain, cabled to a Wi-Fi radio. 6) Output: two printed probes on the board (no connector), into a feed. 7) Any channel width from 20 to 320 MHz. 8) No control wire: the board senses the radio's transmit signal by itself. 9) Output never above 25.0 dBm total per chain. 10) Receive noise figure 4.0 dB or better. 11) DC input 24-60 V. 12) A bare board (PCBA), fitted in our own housing, on our heatsink. Delivered, owned by HI-GAIN: 1) Working sample boards, tested by you. 2) Test results for each sample board. 3) Schematic and PCB layout. 4) Parts list with real part numbers. 5) Feed design. 6) Tune-up procedure. 7) Production files a factory can build from. 8) Firmware, if any. In your bid: 1) Past X-band board work, with photos or measured results. 2) The chips you would use. 3) Your fixed price for all of it. 4) The time it takes. More details will follow with the engineer we choose. Budget: USD 3000–5000
