HMC498LC4 v05.0418 GaAs PHEMT MEDIUM POWER AMPLIFIER, 17 - 24 GHz Typical Applications Features The HMC498LC4 is ideal for use as a LNA or Driver Output IP3: +36 dBm amplifier for: Saturated Power: +26 dBm 23% PAE Point-to-Point Radios Gain: 22 dB Point-to-Multi-Point Radios & VSAT +5V 250 mA Supply Test Equipment & Sensors 50 Ohm Matched Input/Output Military End-Use RoHS Compliant 4x4 mm SMT Package 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.
