Rack-Mount Distribution Amplifiers RMDA Series
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, 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 pushpull hybrid module providing excellent performance and economy for headend applications. The 5500-XX employ dual push-pull 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. The RMDA Series products are housed in a single height, 1.75″ high, rack mountable, aluminum chassis that provides exceptional heat dissipation.
- 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
- Built-in Variable Gain and Slope Controls
Rack-Mount Two-Way Distribution Amplifiers RMDA-ARP
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.
PHC-12G: 1GHz Broadband Passive Headend 12 Channel Combiner
VMM600 Video Modulator
The Drake VMM600 Video Modulator is a professional quality modular headend system designed to optimize rack space.
The VMM600 is a high quality fixed channel heterodyne audio/video modulator. One to twelve modulators can be mounted in the same amount of rack space typically required for two standard size units.
Ideally suited for private cable, hotels and motels, institutional, and SMATV applications, the VMM600 accepts video and audio baseband signals from a satellite receiver, TV camera, videotape recorder, TV demodulator, or similar signal sources.
- Front panel control of RF output level, A/V ratio, and video/audio modulation
- Complies with FCC Rules Part 76
- Rack mount and power supply sold separately
Headend Passive Combiner, 12 Port: Headend Passive Combiner, 12 Port, 5-1000 MHz, Low Loss, RFI Shielded
HPC series consists of 5-1000 MHz passive RF combiners designed for use in a headend to combine the output of up to 32 single-channel devices such as modulators and processors.
HPC is available in 8-, 12-, 24-, or 32-port models. All HPC models feature a compact design, high isolation between ports, low net combining loss, and RFI shielding for minimized egress/ingress interference. A front-panel -20 dB test port (75-ohm “F” type connector) allows testing of the unit’s output without interrupting the service.
