The Cisco® 1.2GHz GainMaker® GaN System Amplifier is the latest-generation broadband amplifier in the Cisco GainMaker platform. Gallium nitride (GaN) technology supports RF output levels up to 57 dBmV. The Cisco GaN amplifier (Figure 1) provides one high-level forward RF output. All Cisco GainMaker products share common plug-in accessories and perform to 1.2 GHz in the forward path. Cisco 1.2GHz GainMaker system amplifier modules have increased gain to allow drop-in for 750-MHz spacing and are mechanically compatible with previous Cisco GainMaker System Amplifier 1.0GHz GMLE housing bases, often allowing upgrade to higher bandwidth with no respacing or resplicing. The DC power supply is modular and located in an updated housing lid for easy access. All Cisco 1.2GHz GainMaker system amplifier modules are factory configured with reverse amplifier, diplex filters, thermal compensation circuit, forward interstage pads, and equalizer to promote optimal performance. Optional single-pilot automatic gain control (AGC) configurations are also available.
