Commercial Distribution Amplifiers

Lindsey Broadband LHA35-RM 1 Ghz

LHA series CATV Distribution Amplifiers with active return are broadband indoor GaAs-Fet / PushPull distribution amplifiers designed for RF distribution systems such as those in Cable Television Apartments, Hotels, Hospitals and other applications where a high quality low noise figure amplifier is necessary to amplify the signals in both the forward and return paths.

Designed with flat operational gain of 35 dB in the forward bandwidth and 18 dB in the reverse bandwidth. They have an input variable equalizer and plug-in interstage equalization feature in the forward bandwidth for balancing , a forward 20 dB gain control and a 20 dB reverse gain control.

Plug in, midstage equalizer modules are available in 2dB steps from 2-26dB.

The amplifiers are self powered and available in 117 and 230 volt.


Features :

GaAs-Fet Push Pull for high output levels with low distortions
Active reverse
Gain and equalization controls
RFI housing
Surge protection on all ports
Diecast aluminium housing for heat dissipation
117 and 230 Volt power

Blonder Tongue Broadband CATV Distribution Amplifier ZCM-48-550

The ZCM-48-550 is an affordable high gain indoor broadband distribution amplifier. The ideal application for this amplifier is for use in a distribution system where the input source is a “cable drop” or the output of a MATV/SMATV headend.

Product Features
  • 550 MHz high gain distribution amplifier
  • Configurable with or without preamp section by external coax jumper
  • Built-in variable gain and slope controls
  • External UL listed power transformer
Additional Information
The ZCM-48-550 provides frequency coverage of 54 to 550 MHz and has a flat 50 dB of operational gain. The amplifier also has built-in variable gain and slope controls. This amplifier uses a single push-pull hybrid module and discrete driver stages,
capable of delivering high output levels with low distortion, even in systems with 77 channels of programming. A separate preamp (18 dB gain) and postamp (32 dB gain) are included with an external RF loop used to provide overall output capability. The ZCM-48 Series products are housed in compact, aluminum chassis that provides excellent heat dissipation. The ZCM-48-550 is provided with an
external UL® listed power transformer.
