Functional Diagram
General Description
The HMC634LC4 is a GaAs PHEMT MMIC Driver Amplifier in a leadless 4 x 4 mm ceramic surface mount package which operates between 5 and 20 GHz The amplifier provides up to 21 dB of gain, +29 dBm Output IP3, and +22 dBm of output power at 1 dB gain compression, while requiring 180 mA from a +5V supply. The HMC634LC4 is an ideal driver amplifier for microwave radio applications from 5 to 20 GHz, and may be biased at +5V, 130 mA to provide lower gain with optimized PAE. The amplifier's I/Os are DC blocked and matched to 50 Ohms with no external matching required.

[1] Reference this number when ordering complete evaluation PCB [2] Circuit Board Material: Rogers 4350
The circuit board used in the final 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.
