1.1 Your Amplifier Package

The FM1000A is a highly efficient amplifier package designed to set a new standard
in FM transmitter design offering modularity, ease of use, and long-term reliabil-
ity. The FM1000A package includes a PA1000 amplifier, PS1000 power supply, and
an FM1K accessory pack.

The PA1000 broadband amplifier requires no tuning and typically provides 80% RF
efficiency across the band. The PS1000 power supply is power factor corrected and
90% efficient. Modern MOSFET technology ensures high AC to RF efficiency
(better than 70% overall) and long-term reliability. The unmatched efficiency of
this power amplifier significantly improves your bottom line by providing cooler
operation and lower power costs.

These modular units are uniquely designed to be lightweight and compact for
convenient shipping, and require only seven RU spaces for installation. Installa-
tion is made simple with just three interconnections between the amplifier and
power supply. In addition, built-in digital metering and status indicator capabili-
ties enable intuitive operation to further augment the user-friendly design.

Economic long-term reliability is ensured through our carefully engineered solid-
state design. The PA1000 features two field-replaceable 500–watt power modules.

This power amplifier delivers 500 to over 1000 watts of RF power output. Use your
existing exciter or purchase the FM1000T which includes our award-winning FM30
exciter for an unbeatable 1 kW transmitter package.
