• The RF Power Tool is designed for non-RF engineers, to evaluate Solid-State RF and prototype innovative solutions

• This modular bench-in-a-box removes the need to invest in a full RF bench while making access to RF easy as a result its intuitive user interface

• Combines an RF generator and test bench capabilities

RF Power Tool Purpose

PA Module box • Power Amplifier lineup with

couplers and sensors • Orange case • Documentation:

• Circuit Information document • Measured data (Pin/Pout, Frequency sweep)

RF Power Tool Setup: In The Box

RF Power Tool box • RF Power Tool • Wall adaptor

− 5 V 3 A universal input with adaptors for various countries.

• SMA – SMA coaxial cable − RF cable suitable for frequencies

from 1 MHz to 5 GHz • 2 HDMI cables

− Used as 4 shielded twisted pair cables, not as digital video cables

• USB cable • PC software • Orange case • Documentation:

− Quick Start guide − Hardware user guide with SCPI command list − GUI (Graphical User Interface) user guide

User Supplied Equipment

• High power supply − Size is 2x rated power of Power Amplifier at rated voltage

of the final transistor − Suggest using TDK Lambda or MeanWell server brick style

• Load − Suggest using Bird or Dielectric labs that are rated for

frequency and power of the PA • Cooling method − Easiest is large heatsink with 6-inch square flat surface to

mount the PA. − 6 x 12, 3-inch high will suffice for 100 W without fan, 250 W with fan

• Connecting cable between PA and load − Be careful to select a cable suitable for the power of the

amplifier and have minimum loss − Bigger is better
