A36xxx RF driver series provides up to 2 Watt output power. Various
types cover a frequency range from 80 to 350 MHz. The frequency is
maximum RF output power is adjustable by an internal potentiometer. The
analogue modulation voltage controls the output power from 0 to 100% of
the adjusted maximum power.
Additional to the analogue modulation voltage a digital modulation
control signal can switch on and off the RF power. An operation scheme
below (page 6) illustrates the interaction of the two modulation signals
the analogue and digital modulation are characterized by extraordinary
on/off ratios of at least 70 dB.
driver can be operated with modulation frequencies (analogue and
digital) up to 1/4 of the carrier frequency.
EMC shielding and mechanical protection is achieved by an aluminium
casing and a conductive surface passivation. The base plate serves for
mounting as well as for heat dissipation.
