The
Pico Macom PIDA series two-way broadband distribution amplifiers are high quali-
ty dual push-pull amplifiers producing forward and reverse signals with extremely low
distortion and high output levels. These amplifiers are designed for bi-directional cable
distribution systems used in institutional and MDU environments, which employ reverse
path signals such as cable modems, remote status monitoring, and remote TV origina-
tion. The
PIDA also makes an excellent headend launch amplifier and is frequently
used in conjunction with
Pico Macom’s passive headend combiners (PHC12G or
PHC24G) to overcome losses associated with signal combining in broadband CATV
systems. Furthermore, the
PIDA can be used in cable systems whose input source is a
franchise cable drop or the output of a SMATV headend. In such applications, the
PIDA
would be used with
Pico Macom’s CEF channel elimination filter for “mix-and-match”
channel selection or for local insertion. The
PIDA enclosure is made of high-grade
aluminum to ensure reliable heat dissipation and corrosion resistance.
Pico Macom
backs up this product with its industry leading 5-year limited warranty.

Braodband Bi-directional Push-Pull Distribution Amplifiers
Available in three forward bandwidth
versions: 50-550MHz (CATV 2-78, 95-99),
50-750MHz (CATV 2-117), and 50-
1000MHz (CATV 2-158)
All versions feature reverse-path
channel bandwidth 5-36MHz (Channels
T7-T11)
Adjustable 30dB forward-path gain and
slope controls for optimal carrier-to-
noise ratio, superior picture quality and
easy system balancing
Reverse-path gain passive or active
mode selection via internal jumpers for
maximum flexibility
Active reverse-path adjustable 20dB
gain control enables balancing of
upstream signal
± 0.75dB flatness across band provides
low distortion and excellent frequency
response
Employs dual state-of-the art push-pull
hybrid technology for very low distor-
tion, high input and output capability
Optional plug-in equalizers and attenua-
tors enable unity gain and slope system
balancing for minimum distortion
Optionally available in power-doubling
version.
-30dB input and output test points
enable simplified setup and perform-
ance monitoring without service
interruption
Shielded enclosure provides over 100dB
RFI shielding performance reducing
leakage and ingress thereby improving
picture quality
Built-in lightning and line-voltage surge
protection protects the unit from dam-
age
Extruded aluminum heat-sink maximizes
heat dissipation for improved reliability
and corrosion resistance
Available in PAL configuration for
international use
External UL approved power supply
