1 v.4 HMC498LC4 Typical Applications Features The HMC498LC4 is ideal for use as a LNA or Driver amplifier for: Point-to-Point Radios Point-to-Multi-Point Radios & VSAT Test Equipment & Sensors Military End-Use Functional Diagram Output IP3: +36 dbm Saturated Power: % PAE Gain: 22 db 2 ma Supply Ohm Matched Input/Output RoHS Compliant 4x4 mm SMT Package 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 +V 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 Ohms for ease of use. The HMC498LC4 eliminates the need for wire bonding, allowing use of surface mount manufacturing techniques.
