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. 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 Electrical Specifications, T A = +25° C, Vdd1, 2, 3 = 5V, Idd = 250 mA* 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 • Test Equipment & Sensors • Military End-Use Parameter Min.
