RF Power Amplifier PA10W
. PA10W – 10 W Power Amplifier Module
1. Overview
The PA10W RF power amplifier comes in a very compact broadband module delivering 10 Watts
RMS (20 Watts PEP, Peak Envelope Power into a 50-ohm load. It has a 3 dB range of 10 MHz to
75 MHz and is powered by a DC +12 V power supply (with the negative terminal grounded . The
PA10W has standard female SMA jacks for RF input and output, and a standard 4-pin ATX
connector for the input DC power. The PA10W typically operates in Class AB. The rise and fall
time for the RF pulse output is typically around 200 ns.
The product comes with blanking circuitry – the blanking circuitry keeps the PA10W blanked
(turned off until a TTL input (logical high is applied to deblank it. 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.
The PA10W module measures 2.25" x 1.4" x 1.4" (57 x 36 x 36 mm . There are multiple
ordering options available, such as enclosures with integrated AC power supplies and enclosures
with a complete RF front-end with preamplifiers and filters for a complete mobile NMR, NQR and
MRI system. See the “Configuration Options” section later in this document for more information.
The use of a low pass (or band pass filter at the output of the PA10W is recommended to reduce
high frequency noise and improve performance.
