The PFAM550 is a professional re-broadcast grade frequency agile double

heterodyne conversion audio/video modulator. Its SAW filter provides superior

sideband filtering, adjacent channel compatibility and spurious free output.

The PFAM550 provides 57±2 dBmV output over 82 channels from CATV

channel 2 to 78 accommodating HRC and IRC offset frequencies. The unit

features a composite audio-video IF loop, which provides compatibility with

encoders, ghost cancellers, and video-override applications. 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, and FCC Docket 21006 offsets are 

standard. Pico Macom backs up this product with its industry leading 5-year

limited warranty.
