In our transition from LV2 to LV2.3, we've decided to move our previous L band amateur television (ATV) system to the S band. We experienced severe interference between the old L band ATV system and our L1 GPS, so instead of the mitigation hacks we did before, we thought just moving it would be a fine idea.
- Must fall in the amateur radio 2.350 - 2.45 GHz band
- Should be small
- Should be light weight
- Should have decent RF connectors, e.g. SMAs.
- Must take (3.3,5,12) V input
- Must emit (1,3,5) W (see link budget page).
We were looking for a separate transmitter and power amplifier, but instead found the BoosterVision BV-M1W-CCD "1 W 2.4 GHz TX/RX Kit w/camera. Some details:
- 1 W transmitter
- 78mm x 51mm x 18mm, but seems pretty hackable for size.
- 5 channels: 2.390, 2.410, 2.430, 2.450, and 2.470 GHz
- Whole system (TX, RX, camera) takes 11.1 - 12.8 V
We've already tested the units indoors, and they seem to work well.
Like the telemetry system, we want to hit the middle of the channel range so that we can move the channel in order to better match whatever the actual frequency of the constructed CPA is. That would mean targeting 2.430 GHz.
