The amplifier is designed to be powered from either an external +48 VDC source or an optional internal AC power supply. Model User Manual 040003A010 Rev A Page 4 of 25 GA amplifiers cover the 406-420 MHz band without retuning. Model HA amplifiers cover the 450- 470MHz band without retuning. Amplifier specifications are shown in Table 1-1. There are seven input ranges available as shown in Table 1-2. Closed loop power control is used to maintain a constant output power under varying voltage, signal input level, frequency and output load conditions. Several design features work to protect the amplifier under adverse conditions. The amplifier is designed to fit into 5.25 inches (3RU) of vertical 19-inch rack space. The front panel includes LED indicators for monitoring status and alarm conditions. This information is also accessible via a monitor connector on the rear of the amplifier. The fan assembly draws ambient air in from the front and blows the air across the heat sink fins out the back of the amplifier. NOTE: The manufacturer’s rated output power of this equipment (see Table 1-1) is specified for single carrier operation using constant-envelope modulation. This equipment is NOT designed for multiple-carrier operation, nor is it intended to be used with non- constant envelope modulation waveforms.

Tuning Procedure The Crescend Technologies High Power UHF RF power amplifier is designed for paging and other applications that use a single carrier constant envelope waveform. The amplifier is designed to be powered from either an external +48 VDC source or an optional internal AC power supply. Model GA amplifiers cover the 406.1-421 MHz band without retuning. Amplifier specifications are shown in Table 1-1. There are seven input ranges available. Closed loop power control is used to maintain a constant output power under varying voltage, signal input level, frequency and output load conditions. Several design features work to protect the amplifier under adverse conditions. As indicated above, there are no tuning procedures for the amplifier.
