HMC519LC4 v02.1208 LOW NOISE AMPLIFIERS - SMT 8 GaAs PHEMT MMIC LOW NOISE AMPLIFIER, 18 - 31 GHz Typical Applications Features The HMC519LC4 is ideal for: Noise Figure: 3.5 dB • Point-to-Point Radios Gain: 14 dB • Point-to-Multi-Point Radios & VSAT Output IP3: +23 dBm • Test Equipment & Sensors Single Supply: +3V @ 75 mA • Military & Space 50 Ohm Matched Input/Output 24 Lead Ceramic 4x4mm SMT Package: 16mm2 Functional Diagram General Description The HMC519LC4 is a high dynamic range GaAs PHEMT MMIC Low Noise Amplifier (LNA) housed in a leadless 4 x 4 mm ceramic surface mount package. The amplifier operates between 18 and 31 GHz, providing 14 dB of small signal gain, 3.5 dB noise figure and output IP3 of +23 dBm, while requiring only 75 mA from a +3V single supply. The P1dB output power of +11 dBm, enables the LNA to function as a LO driver for balanced, I/Q or image reject mixers. The HMC519LC4 also features I/Os that are DC blocked and internally matched to 50 Ohms, making it ideal for microwave radio and VSAT applications.

The circuit board used in this application should use RF circuit design techniques. Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation board should be mounted to an appropriate heat sink. The evaluation circuit board shown is available from Hittite upon request.
