Low Gain Dual System Amplifier

1 GHz with 65/86 MHz Split

Description

The GainMaker ® Broadband Amplifier Platform includes a variety of RF amplifiers that address the divergent needs of today’s broadband networks. All GainMaker amplifiers provide superior 2-way performance and reliability combined with a user-friendly layout. All share common plug-in accessories and perform to 1 GHz in the forward path. The

System Amplifiers in this family provide multiple forward RF output ports while the Line Extenders provide a single forward

RF output port.

GainMaker System Amplifiers now utilize GaAsFET technology in the interstage and output gain stages for improved distortion performance.

The GainMaker System Amplifier modules have increased gain and are mechanically compatible with previous

System Amplifier II, II+, and III housing bases, often enabling upgrade to higher bandwidth with no re-spacing or re-splicing. The DC power supply is modular and located in an updated housing lid for easy access. All

GainMaker System Amplifier modules are factory configured with reverse amplifier, diplex filters, thermal compensation circuit, forward interstage pads, and equalizer to ensure optimal performance. Optional single-pilot

Automatic Gain Control (AGC) configurations are also available.

The GainMaker Low Gain Dual System Amplifier is ideally suited for providing high (bridger) level RF to the feeder network. It provides two forward RF outputs (Main and Auxiliary) with the option to create a third RF output via the use of an optional plug-in Auxiliary path signal director.

Features

• Common RF test points for forward output and reverse injection simplify reverse balancing

• Increased forward gain

• High-performance GaAsFET gain stage technology

• Fixed-value, plug-in accessories are common to all GainMaker products

• 60 and 90 volt AC powering capability

• 15 ampere current capacity (steady state) and 25 ampere surge survivability

• Optional 3-state reverse switch (on/off/-6 dB) allows each reverse input to be isolated for noise and ingress troubleshooting (status monitoring required)

• AGC has Thermal backup, which eliminates disruptive RF output variation in the event of pilot loss

• Improved hum modulation

• Plug-in, self-contained diplex filters

• Modular high-efficiency power supply allows simplified maintenance

• Reverse input pad and RF test point for each reverse input port allow optimum reverse path design and alignment

• Directional Coupler RF test points provide best accuracy

• Surge resistant circuitry ensures gain stage protection without fuses or other nuisance failure causing devices

Data is based on stations configured for 2-way operation. AC currents specified are based on measurements made with typical CATV type ferro-resonant AC power supply (quasi-square wave), and standard GainMaker System Amplifier power supply (2.2 amp, 24 V DC, pn 734771).

DC supply has a user configurable 30 V, 40 V, or 50 V AC under voltage lockout circuit. Default setting is 30 V. 40 V or 50 V

AC under voltage lockout may be selected by changing the position of the lockout jumper.

Notes:

1. Reference output tilt is specified as “LINEAR” tilt (as opposed to “cable” tilt).

2. Forward Gain and Noise Figure measured with 0 dB input EQ and 1 dB input pad.

3. Down tilt, the effect of cable, is represented by a (-). Up tilt, the effect of cable equalization, is represented by a (+). Forward internal tilt specified is primarily due to an on board equalizer and a factory configured 10.5 dB plug-in interstage equalizer.

4. Loaded with 64 PAL B/G CW carriers from 112-600 MHz. Digital refers to 600-1002 MHz loading with QAM carriers at -6 dB relative to analog CW carrier levels.

5. X-mod (@ 15.75 kHz) specified using 100% synchronous modulation and frequency selective measurement device.

6. Reverse Gain and Noise Figure for station with 0 dB reverse input pad, 0 dB reverse output EQ, and 1 dB output pad.

7. Reverse Operational Gain, Noise Figure, and Return Loss are specified without reverse switch option. If switch is installed, reduce Gain by 0.5 dB, increase Noise Figure by 0.5 dB, and decrease Return Loss by 1 dB.

8. Measured and specified as Composite Beat .

9. Tested per CENELEC Standard EN50083-3, with reference output tilt. RF output level specified is at 1002 MHz (forward).

10. Loaded with 64 PAL I CW carriers from 88-600 MHz .

Digital refers to 600-1002 MHz loading with QAM carriers at -6 dB relative to analog

CW carrier levels.

11. Loaded with 78 NTSC CW carriers from 91-550 MHz. Digital refers to 550-1002 MHz loading with QAM carriers at -6 dB relative to analog CW carrier levels.
