HMC498LC4 v02.1208 GaAs PHEMT MEDIUM POWER AMPLIFIER, 17 - 24 GHz Typical Applications The HMC498LC4 is ideal for use as a LNA or Driver amplifier for: • Point-to-Point Radios • Point-to-Multi-Point Radios & VSAT Features Output IP3: +36 dBm Saturated Power: +26 dBm @ 23% PAE Gain: 22 dB +5V @ 250 mA Supply 50 Ohm Matched Input/Output RoHS Compliant 4x4 mm SMT Package 11 LINEAR & POWER AMPLIFIERS - SMT • Test Equipment & Sensors • Military End-Use Functional Diagram General Description The HMC498LC4 is a high dynamic range GaAs PHEMT MMIC Medium Power Amplifier housed in a leadless “Pb free” SMT package. Operating from 17 to 24 GHz, the amplifier provides 22 dB of gain, +26 dBm of saturated power and 23% PAE from a +5V supply voltage. Noise figure is 4 dB while output IP3 is +36 dBm typical enabling the HMC498LC4 to function as a low noise front end as well as a driver amplifier. The RF I/Os are DC blocked and matched to 50 Ohms for ease of use. The HMC498LC4 eliminates the need for wire bonding, allowing use of surface mount manufacturing techniques.

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.
