PCS LPF-7000 FM 1500W LOW PASS FILTER with DIGIAMP
1500W Low Pass filter with easy connect DIGIAMP system, built for our MAX PRO
5015 series exciters. The DIGIAMP interconnect system enables easy integration
into a FM transmitter. All it takes is one flat cable (DIGIAMP). This connection
enables measurement of SWR and Power, amplifier supply voltage and current and
amplifier temperature. It also provides SWR protection and automatic output level
limiting. Of course it also includes low pass filter as RF amplifiers produce
harmonics at even multiples of fundamental frequency. If your harmonics fall on
or near a TV channel or Maritime frequency you could cause severe interference
to that channel. The most common cause of fines from federal agencies is due to
TVI or other interference from your transmitter which generates a complaint. Use
of the nicely priced PCS 7000 low pass filter is the best method of eliminating
this kind of interference. The low insertion loss of the PCS-7000 filters makes
them well suited for use at power levels as low as 1 watt on up to 1500 watts!
These units are constructed using PTFE laminate, high-quality 1KV mica capacitors
and machine formed silver-plated coil wire! SWR and PWR voltages are provided
for power/swr measuring purpose. Two calibrating trimmers are provided as well
to adjust correct power and swr measurment accuracy. SWR protection circuitry
is provided as well and its sensitivity can be adjusted with one of the trimmers
(requires MAX PRO 3000, 5015 or 4025). When reflected power (SWR) reaches certain
level swr protection output decreases RF output. ALC automatic level control also
requires MAX PRO 4025+, 5015+ or 3000+.
A perfect companion for the pallet amplifiers, offering output filtering and swr protection!
