PA100W RF Power Amplifier
2. Specifications
DC Electrical Specifications
Table 1: Electrical specifications for the PA100W RF power amplifier.
Parameter Specification Units
Max DC Input Voltage 28 V (DC)
Max RF input power 2.3 W
Max. continuous RF output power* 100 W (RMS)
TTL De-blanking Voltage 3.3 V
*NOTE: Operating at this power level requires an adequate heat dissipation and an
appropriate rated power supply.

10 MHz 0.64
20 MHz 0.86
30 MHz 1.02
40 MHz 1.08
50 MHz 1.02
60 MHz 1.02

Table 2 shows data for the PA100W when supplied by +28 V. The PA100W is capable of
outputs greater than 100 W - however, it is important not to exceed the input power parameters for
the specific operating frequency (Table 2) to avoid damaging the module. Also note that if the
power amplifier is supplied by a +24 V DC source the gain is reduced and a maximum value of
approximately 150 W PEP can be achieved.
