HMC921LP4E
v02.0312
GaAs HBT MMIC 2 WATT
POWER AMPLIFIER, 0.4 - 2.7 GHz
2150 MHz Evaluation PCB
The circuit board used in this application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used
to connect the top and bottom ground planes.
The evaluation board should be mounted to an
appropriate heat sink. The evaluation circuit board
shown is available from Hittite upon request.
