PCM55SAW
550MHz Single-Channel PLL SAW-filtered A/V Modulator
The Pico Macom PCM55SAW is a professional grade microprocessor con-
trolled phase-locked loop synthesized single channel 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 field 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
and greater frequency stability and higher spurious free adjacent channel per-
formance is required. Its phase locked loop frequency control, and superior
SAW filtering enhances stability, minimizes adjacent channel interference and
assures accurate and spurious free output. Superior out-of-band carrier-to-
noise performance is achieved through band-pass filtering at the output amplifi-
er. 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.
