Where to put a 300Ω to 75Ω balun
Indeed, a balun always goes between coax and twin-lead, whether it's at the receiver, antenna, or anywhere inbetween. It can be placed in-line just fine. …

Why is the balun transformer shorted and not simply removed?
Transmission line transformers are used, so that the upper transformer, while it may not see any voltage drop across the windings (nominally), it is still used as a delay. It may be wound on a hollow …

LVDS to Singled-Ended - Transmission Line Balun Matching
Notice page 3, "Differential Output Impedance", which rises with frequency; and Fig.16. Most likely they wanted a load resistor to dampen this, and then series resistors to match to 50/100 ohm output …

How does a planar balun work (ie, microstrip <-> stripline)?
What they have, is a combination matching/balun stub, approx. λ/4 long, which affords feedline choking (stub balun) and probably some impedance matching. … So it's a lot harder to say it's nearly enough for a proper λ/4 balun function.
So at last: the taper section. …
