A pair of car batteries used on a /P expedition could easily discharge to 20V. The modern high power DMOS devices (for 1.3, 2.3 and 3.4 GHz) that this PSU is aimed at powering like a constant 28V Vcc so a straightforward SMPSU looks the obvious solution. If two batteries have to be used, then used in parallel they can be charged together from a car engine.

Also, the same PSU design can be adapted for 50V devices which would need 4 batteries in series.


Good reason, it is just that the EMC engineer in me has a pronounced dislike of
any switching devices near radios!
