drop-in channel expansion

57dBmV output for optimum 
carrier-to-noise performance

Carrier-to-noise ratio >60dB 
provides superior picture quality

Front panel test point for easy 
RF level system monitoring

Composite audio-video IF loop
provides compatibility with
encoders, ghost cancellers, and
video-override applications

IRC and HRC offset available 
allows for easy frequency set-
tings in systems using offset
channels

Double heterodyne conversion
provides superior spurious har-
monic output suppression

The PFAM550SUB is a professional re-broadcast grade frequency agile double
heterodyne conversion audio/video modulator that allows RF return of audio-
video 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 com-
patibility 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 56±1dBmV 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.
