PCM55SAW
550MHz Channelized-Agile PLL SAW-filtered A/V Modulator
PCM55SAW
550MHz Channelized-Agile PLL SAW-filtered A/V Modulator
The Pico Macom PCM55SAW is a professional grade microprocessor controlled
phase-locked loop synthesized channelized-agile audio-video modulator. The
PCM55SAW provides a full 55dBmV minimum output from sub-band channels
T7 through T13, and CATV channels 2 to 78 including channels 95 to 99 while
accommodating HRC and IRC offset frequencies (5.75-550MHz). The unit is
lab re-tunable within band via internal dip-switch channel selection and minimum
output filter retuning. This modulator is used in more heavily channel-loaded
systems and where cost effective expansion up to 550MHz is desired. Its phase-
locked loop frequency control, and superior SAW filtering enhances stability,
minimizes adjacent channel interference and assures accurate and spurious free
output. The modulator is equipped with a pre-emphasis disable switch which
enables pass-through of high-fidelity BTSC stereo signals where available.
Superior out-of-band carrier-to-noise performance is achieved through band-
pass filtering at the output amplifier. The modulator is shipped with all internal
adjustments preset. FCC Docket 21006 offsets are standard. Pico Macom
backs up this product with its industry leading 5-year limited warranty.
