HMC498LC4 v05.0418 GaAs PHEMT MEDIUMPOWER AMPLIFIER, 17 - 24 GHzTypical ApplicationsFeatures 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 • Point-to-Multi-Point Radios & VSAT +5V @ 250 mA Supply S - S • Test Equipment & Sensors 50 Ohm Matched Input/Output R • Military End-Use RoHS Compliant 4x4 mm SMT Package IE LIF Functional DiagramGeneral Description P The HMC498LC4 is a high dynamic range GaAs M PHEMT MMIC Medium Power Amplifier housed in a leadless “Pb free” SMT package. Operating from 17 R A 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. The RF I/Os are DC blocked and matched to 50 Ohms for ease of use. The HMC498LC4 eliminates the R & P need for wire bonding, al owing use of surface mount A manufacturing techniques.
