MODULATOR, 55 dB, SAW FILTER CH. 2-36Pico Macom Modulator, Saw Filter

Specify Channel 2-36

The Pico Macom PCM55 SAW 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 phaselocked 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 bandpass filtering at the output amplifier. The modulator is shipped with all internal adjustments preset. FCC Docket 21006 offsets are standard.
