It is assumed that during the pulse, 0.5A is delivered by the
battery, and 1.5A by the capacitor.
Conclusion: High capacitance is needed to minimize voltage
drop. A high value capacitance, even with a higher ESR,
results in a lower voltage drop. Low voltage drop minimizes
the conductive and emitted electro magnetic interference,
and increases transmitter output power and efficiency.
MOUNTING SOLUTIONS:
1. Parts with 2mm height that can be mounted on the board.

2. Smaller parts, consuming
less PCB real estate and
with flexible termination
tabs, enable mounting the
capacitor by cutting the
PCB and placing the
capacitor as shown in
the drawing, utilizing the
PCMCIA housing height.
