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