Functional Diagram
General Description
The HMC499LC4 is a high dynamic range GaAs PHEMT MMIC Medium Power Amplifier housed in a leadless "Pb free" RoHS Compliant SMT package. Operating from 21 to 32 GHz, the amplifier provides 16 dB of gain, +24 dBm of saturated power and 16% PAE from a +5.0 V supply voltage. The RF I/Os are DC blocked and matched to 50 Ohms for ease of use. The HMC499LC4 eliminates the need for wire bonding, allowing use of surface mount manufacturing techniques.

[1]
[1] Reference this number when ordering complete evaluation PCB [2] Circuit Board Material: Rogers 4350.
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.
