| HMC752LC4 v00.0409 GaAs HEMT MMIC LOW NOISE AMPLIFIER, 24 - 28 GHz Features Noise Figure: 2.5 dB Gain: 25 dB P1dB Output Power: +13 dBm Supply Voltage: +3V @ 70 mA Output IP3: +26 dBm 50 Ohm matched Input/Output 24 Lead Ceramic 4x4mm SMT Package: 16mm2 8 LOW NOISE AMPLIFIERS - SMT Typical Applications This HMC752LC4 is ideal for: * Point-to-Point Radios * Point-to-Multi-Point Radios * Military & Space * Test Instrumentation Functional Diagram General Description The HMC752LC4 is a GaAs MMIC Low Noise Wideband Amplifier housed in a leadless 4x4 mm ceramic surface mount package. The amplifier operates between 24 and 28 GHz, providing up to 25 dB of small signal gain, 2.5 dB noise figure, and output IP3 of +26 dBm, while requiring only 70 mA from a +3V supply. The P1dB output power of up to +13 dBm enables the LNA to function as a LO driver for balanced, I/Q or image reject mixers. The HMC752LC4 also features I/Os that are DC blocked and internally matched to 50 Ohms, making it ideal for high capacity microwave radios or VSAT applications.

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.
