Proto Rev 1.3 by mikenye · Pull Request #5 · plane-watch/hardware

mikenye · 2026-06-24T06:02:10Z

Bump the plane watcher prototype from rev 1.2 to rev 1.3, addressing the issues highlighted in #4, and discussed on Discord.

Resolves #4.

@shaneshort are there any other changes we want to make before we merge this and get another batch of prototypes fabricated?

- We were overloading the output of the ADL5513, with gain/feedback resistors with resistance too low. - Change R37, R38, R39 and R40 values from 499Ω to 4.7kΩ

- Add R44 (0Ω) & R45 (DNP, footprint only), allowing for replacement to adjust slope. - Add C61 (DNP, footprint only), allowing for output filtering to reduce output bandwidth if needed.

Bump up series resistor to 1kΩ from 58Ω (lol)

Cf in datasheet, figure 42.

…r noise offset - Implement low-pass filter to output noise floor with no pulses - Feed noise floor into ADC driver -IN to improve range/sensitivity - Buffer low pass filter output - Buffer log detector output with spare op amp in OPA2320 package - Tidy schematic & vias

Voltage divider sets the ADL5513 TADJ pin to approximately 0.85 V for 1090 MHz operation

net class "RF_50Ω" now 0.34544mm trace width.

Add footprints for RF input tuning:

RF_IN ── J1 ── ESD ── [SER1] ──●── [SER2] ──●── LNA/FILTER_IN
                              │             │

                             GND           GND

LNA input stability resistor

Immediately before the LNA input, add:

Name: R_STAB_IN
Default: 0 Ω
Package: 0402
Purpose: optional small series damping

Immediately after the LNA output, before the next filter/match:

Name: R_STAB_OUT
Default: 0 Ω
Package: 0402

Same for second LNA.

TODO: Replace ADC Driver gain & feedback resistors to 499 ohm now that output of log detector is buffered.

Done: 4cf9079

Default: series 0R, shunts DNP. Populate after VNA/S11 testing to compensate ESD/bias-tee/LNA input parasitics.

Add DNP RF tuning footprints around the input match, SAW filter ports, and log detector input path. Update schematic annotations for VNA-populated C/L/R matching options, mark AD8138 feedback caps as optional, and update the PCB layout for the new RF frontend tuning network.

…ine in high traffic areas

- Add extra RF bypassing on AD9203 supply/reference nodes - Add 100pF, 1nF, and 10uF bypassing on AD8138 VOCM - Reroute ADC-area traces in an attempt to reduce clock coupling into sensitive nodes

- Reposition 3V3A decoupling and clean up nearby supply routing - Add GND stitching around ADC clock, reference/VOCM, and analog rail areas - Add extra ground returns near sensitive analog/noise-floor routing - Refill copper zones after the layout changes

Change ADC gain/feedback network resistors to higher value

4c48fe0

- We were overloading the output of the ADL5513, with gain/feedback resistors with resistance too low. - Change R37, R38, R39 and R40 values from 499Ω to 4.7kΩ

Add footprints for ADL5513 slope adjustment and output filtering
