PA100W RF Power Amplifier
II. PA100W – 100 W Power Amplifier Module
1. Overview
The PA100W RF power amplifier comes in a very compact broadband module delivering
100 Watts RMS (200 Watts PEP, Peak Envelope Power) into a 50-ohm load. It has a frequency
range of 10 MHz to 100 MHz and is powered by a DC +24 to +28 V power supply (with the negative
terminal grounded). The PA100W has standard female SMA jacks for RF input and output, and a
screw terminal block for the DC power input. The PA100W typically operates in Class AB. The rise
and fall time of the RF pulse output is approximately 200 ns.
The product comes with blanking circuitry – the blanking circuitry keeps the PA100W blanked
(turned off) until a TTL input (logical high) is applied. The blanking circuitry helps to conserve
power, keeps the amplifier cool under typical operating conditions, and provides noise reduction
during the reception of NMR signals. To enable (deblank) the power amplifier, a TTL pulse (logical
high) needs to be applied to the control circuitry.
The PA100W power amplifier module measures 3.15" x 2.54" x 2.33" (80 x 65 x 59 mm). It can
be delivered as a module (with the blanking circuitry) or in various enclosures - see the
“Configuration Options” section later in this document for more information.
