The PFAM550SUB is a professional re-broadcast grade frequency agile double heterodyne conversion audio/video modulator that allows RF return of audiovideo signal from a remote location on bi-directional cable systems. It is ideal for use in institutional applications requiring remote TV origination. The PFAM550SUB features a composite audio-video IF loop, which provides compatibility with encoders, ghost cancellers, and video-override applications. Its SAW filter provides superior sideband filtering, adjacent channel compatibility, and spurious free output. The PFAM550SUB provides 56dBmV output from sub-band channels T7 through T13, CATV channels 2 to 78 including channels 95 to 99 while accommodating HRC and IRC offset frequencies (5.75-550MHz). Front panel DIP-switch controlled phase-locked-loop (PLL) allows easy channel selection and drift-free channel stability. High quality modulation and RF level control potentiometers assure years of reliable operation. The modulator is shipped with all internal
adjustments pre-set. FCC Docket 21006 offsets are standard. Pico Macom backs up this product with its industry leading 5-year limited warranty.
