Description

The Pico Macom PM45 is a professional grade phase-locked loop synthesized channelized-agile audio-video modulator. This modulator provides 45dBmV minimum
output on CATV channels 2 to 125 (54-806 MHz) while accommodating HRC and IRC offset frequencies. The PM45 features a composite audio-video
IF loop, which provides compatiblility with encoders, ghost cancellers, and video-override applications. The unit can be reconfigured to any output channel
by qualified service centers. This cost effective modulator can be used to expand systems using PCM55, PCM555AW and PLM55 modulators beyond 300MHz, where the expansion does not require modulators with higher output levels. The PM45 provides the greater frequency stability and higher adjacent channel performance required in such expansions. The modulator is equipped with a pre-emphasis disable switch which enables pass-through of high-fidelity BTSC stereo signals where available. 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-ofband carrier-to-noise performance is achieved through band-pass filtering at the output amplifier. The PM45 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 warranty.
