Performance of the Final Production Board

Version 1v0 is our final design, the one that will go into production soon and that backers will receive in November. This version will have a number of additional amateur radio bands (50/70 MHz, 220 MHz, and 920 MHz) that were not included in the 0v3 prototype. The 1280 MHz band will be updated as well.

In order to assess the performance of the final LimeRFE 1v0 board, we have combined measurements from the prototype with simulated results for new or modified bands. The expected performance of the production board is summarised in the table below:

No. Band TX Gain [dB] TX OP1dB [dBm] RX Gain [dB] RX NF [dB] RX IIP3 [dBm]
1 WB 1000 27 min, 45 max 22 min, 28.5 max 17 min, 21 max 4 min, 6 max 12 min, 17 max
2 WB 4000 12 min, 34 max 15.5 min, 24 max 6 min, 19 max 1.5 min, 4 max 13 min, 22 max
3 HAM 30 (5-30 MHz) 31 nom 32.5 nom 20 nom 5 nom 14 nom
HAM 30 (1-5 MHz) 31 nom 32.5 nom 20 nom - 3 min, 14 max
4 HAM 50-70 * 30 nom 29 nom 18 nom 5.5 nom 13 nom
5 HAM 145 23 nom 35.5 nom 18 nom 7 nom 11 nom
