Not sure if this is worth the effort, but...
Booster's gain is actually a bit too high. In hindsight 30dB is probably plenty (maybe 35dB abs max). Using with Urukul we end up having to run with ~20dB attenuation for a 1W output. Internally booster already has a 5dB attenuator to reduce the gain. That means we end up attenuating by ~25dB which is silly from a noise POV.
The PHA-1+ has something like 16dB of gain. If we scrap the internal 5dB and 6dB attenuators and go for a gain of 35dB then we could scrap it completely. This would simply the design and reduce cost and power consumption.
The matching networks might need tweaking, but I guess those are tuned at production time anyway so may not be an issue?
Maybe it's not worth the effort, but I thought I'd mention it, as it would make a somewhat better final product. What do you think @gkasprow
