CMPA0060025D Datasheet, PDF (4/7 Pages) Cree, Inc – 25 W, 20 MHz - 6.0 GHz, GaN MMIC, Power Amplifier
Functional Block Diagram
This device employs a wideband amplifier topology.It has an internal termination for the Gate, which works well
over 1.0-6.0 GHz. For operation below 1.0 GHz an external termination is required. This termination needs to be DC-
blocked and suitable to withstand up to 2 W of RF power. (Refer to the reference design section for the LF-termination
in this data sheet for more details). The circuits also require external wideband Bias –T’s to supply voltage to the Gate
and Drain. The Bias-T at the Drain needs to be designed to handle 50 V and up to 2.0 A.
