Ripple filter

It is necessary to connect a low saturation transistor (2SA1362 etc.) for ripple filter, because this IC

doesn’t have transistor for ripple filter. Care should be taken to stabilize the ripple filter circuit,

because the ripple filter circuit supplies internal circuit except power drive stage with power source.

Capacitor

Small temperature coefficient and excellent frequency characteristic is needed by capacitor below.

• Oscillation preventing capacitors for power amplifier output

• Capacitor between RF OUT and GND
