RMDA Series

Rack-Mount Distribution Amplifier

969 Horsham Road lHorsham, Pennsylvania 19044 USA l Phone: [phone] Fax: [phone] [e-mail]

Features

• Rack Mount - 1 EIA (1.75”) Spacing, Rugged Aluminum
Chassis

• Available in Frequency Ranges up to 1000 MHz

• Push-Pull and Power Doubling Models for High Output and
Low Distortion

• Built-in Variable Gain and Slope Controls

• C-UL Listed

The RMDA Series are professional quality, broadband, rack­mounted hybrid distribution amplifiers. The RMDA’s are ideal
as a headend launch amplifier or distribution amplifier for
MATV, SMATV or CATV applications requiring rack mounting.
A variety of models are available with operational gains of 15,
30, 43 or 50 dB and frequency ranges from 47 to 450, 550,
750, 860 or 1000 MHz. Refer to the RMDA specifications for
available gain and bandwidth combinations.

The RMDA Series amplifiers have built-in variable gain and
slope controls. The 5500S-XX models use a single push-pull
hybrid module providing excellent performance and economy
for headend applications. The 5500S-XX employ dual push­pull hybrid modules and the 5500P-XX have a push-pull hybrid
followed by a power doubling hybrid. The dual hybrid models
will have better CNR performance, compared to single hybrid
models in applications with low input levels coupled with
reduced gain settings. Test ports for both the input and output
are provided for monitoring signal levels without interrupting
service (not available on 5500S-XX). The RMDA Series prod­ucts are housed in a single height, 1.75” high, rack mountable,
aluminum chassis that provides exceptional heat dissipation.

The RMDA-ARP (active return path) are rack mounted 2-way broadband distribution amplifiers. Utilizing push-pull hybrid
amplifier technology, they are ideal for MATV, SMATV or CATV applications. The amplifiers have a forward bandwidth of
54-860 MHz with a gain of 30 dB. The reverse path of 5-40 MHz is field configurable for active or passive operation.

The RMDA-ARP amplifier has built-in variable gain controls on both the forward and reverse paths. A forward path vari­able slope control is provided inter-stage as is the variable gain control. Additionally, a fixed forward equalizer and for­ward and reverse attenuator plug-ins can be installed for further signal conditioning at the input to the amplifier. 30 dB
back-matched test ports at the input and output are provided for monitoring both forward and reverse signal levels with­out interrupting service. The amplifier is housed in a 1RU aluminum chassis that provides exceptional heat dissipation.
