+<h3>SparkFun Electronics' preferred foot prints</h3>
+In this library you'll find connectors and sockets- basically anything that can be plugged into or onto.<br><br>
+We've spent an enormous amount of time creating and checking these footprints and parts, but it is the end user's responsibility to ensure correctness and suitablity for a given componet or application. If you enjoy using this library, please buy one of our products at www.sparkfun.com.

+You are welcome to use this library for commercial purposes. For attribution, we ask that when you begin to sell your device using our footprint, you email us with a link to the product being sold. We want bragging rights that we helped (in a very small part) to create your 8th world wonder. We would like the opportunity to feature your device on our homepage.
+
+
+<b>SMA Antenna Connector</b><p>
+This is a footprint for an edge mount RF antenna. Works pretty well with SMA type connectors but may also work with other edge mount RF connectors. Keep in mind, these edge mount connectors assume you are using a 0.062" PCB thickness.

+<b>SMA Antenna Connector</b><p>
+This is a footprint for an edge mount RF antenna. Works pretty well with SMA type connectors but may also work with other edge mount RF connectors. Keep in mind, these edge mount connectors assume you are using a 0.062" PCB thickness.

+This footprint was designed to help hold the alignment of a through-hole component (i.e. 6-pin header) while soldering it into place.
+You may notice that each hole has been shifted either up or down by 0.005 of an inch from it's more standard position (which is a perfectly straight line).
+This slight alteration caused the pins (the squares in the middle) to touch the edges of the holes. Because they are alternating, it causes a "brace"
+to hold the component in place. 0.005 has proven to be the perfect amount of "off-center" position when using our standard breakaway headers.
+Although looks a little odd when you look at the bare footprint, once you have a header in there, the alteration is very hard to notice. Also,
+if you push a header all the way into place, it is covered up entirely on the bottom side. This idea of altering the position of holes to aid alignment
+will be further integrated into the Sparkfun Library for other footprints. It can help hold any component with 3 or more connection pins.

+R18 is necessary to prevent the signal from floating
+when there is no external hardware switch. This may be the
+case with the "bare bones" UART breakout, for instance,
+where the switch is optional.
+This is a cost effective UART pin protection scheme.
+Since the UART is not buffered, it must be protected from
+excess voltages in case it's miswired.
+
+These Zeners will clamp to ~3.6V. Both MCU pins are 5V tolerant,
+so there is no risk.
+General purpose TVS diodes for each I/O (except UART).
+They add an extra layer of protection to the buffer MOSFETs.

+Power
+To hedge against shortages of the LDFPVR, there are two stuffing options for powering the PA:
+The regulator or the Zener + NPN combo. Both have been validated with a "normal" 12V
+battery range (11.5-14.5V).
+
+The regulator option will work with voltages down to 9V. The Zener option will need a much smaller
+inline resistor to regulate under load with a 9V input, but this will also increase quiescent
+current way too much. So tightening the input voltage requirement is the most reasonable thing
+to do. There is no real need for an AIS unit to operate from 9V. Such batteries have poor energy
+density anyway and shouldn't be used here.

+This 3-pole Chebyshev has a measured insertion loss of only 2.6dB in the passband.
+It is sharp enough to bring FM radio and aviation aids (~200MHz)
+near or below the AIS band, but not selective enough to decimate VHF television
+between 174 and 180MHz.
+
+If this becomes an issue a SAW filter may be used, but they're nearly impossible
+to source right now (and much more expensive).

+The design uses a Class E configuration for 162MHz.
+Practical testing proved that it yields adequate power
+to drive the PA stage.
+
+Any of these ICs will work here:
+Si4463
+Si4460
+Si4467
+
+Firmware sets the TX power level differently for each.
+For RX, both IC inputs are configured as single-ended with no matching network.
+Practical field testing suggests there is no need for one.
+
+Any of these ICs can work here: Si4460, Si4467, Si4362, Si4463.

+RF Power Amplifier
+MAIANA™ AIS Transponder
+Copyright © 2015-2020 Peter Antypas
+Licensed under GPLv3
+This power amplifier adds almost 20dB of gain for a total
+conducted output power of +33dBm.
+
+It is based on the reference designs in the datasheet, but
+includes a narrowband input matching network to reduce BOM
+and a very steep Chebyshev low pass filter to deal with a
+pesky 2nd harmonic that falls in the restricted aviation band (324MHz).
+
+The MOSFET drain is always powered, but the gate bias voltage
+is turned on via R11, R12, C11 and L17. The RC delay is essential for suppressing
+spurious emissions during ramp up and ramp down.
+
+This MOSFET is at End Of Life. NXP recommends the AFT05MS004N
+as a replacement, but it's not a drop-in; it will need different
+matching networks, biasing and input power.
+
+Last time buy for this MOSFET is end of 2021 and there is ample supply,
+so there is no rush to design it out.

+The GNSS RTC is always powered, but its main voltage rail is only turned on explicitly
+via firmware. This scheme was necessary to prevent the UART output from
+hijacking the ST ROM bootloader during firmware update. With the migration to a new
+bootloader this isn't necessary anymore, but I'm leaving it in for now.
+
+The matching network adjusts the tuning of the antenna in the PVC enclosure which
+is very different from free space.
+
+There is no VIO pin in the Quectel modules, so it's left unconnected. I added this to
+accommodate UBlox as possible substitutes, but that's not going to happen. The
+L76L-M33 performs better than any of them at half the price.

+This is a reasonably good RF switch which does not need DC blocking caps.
+
+That said, it requires control voltages to be below 2.7V, so a voltage
+divider was added. RX_EN must be high during RX
+
+The 9 test pads here form a footprint for a coaxial pogo pin probe in the test jig.
