HMC518_09

HMC518 v01.0907 GaAs PHEMT MMIC LOW NOISE AMPLIFIER, 20 - 32 GHz 1 LOW NOISE AMPLIFIERS - CHIP Typical Applications The HMC518 is ideal for use as a LNA or driver amplifier for: • Point-to-Point Radios • Point-to-Multi-Point Radios & VSAT • Test Equipment and Sensors • Military & Space Features Noise Figure: 3 dB Gain: 15 dB OIP3: 23 dBm Single Supply: +3V @ 65 mA 50 Ohm Matched Input/Output Die Size: 2.27 x 1.32 x 0.1 mm Functional Diagram General Description The HMC518 chip is a high dynamic range GaAs PHEMT MMIC Low Noise Amplifier (LNA) which covers the 20 to 32 GHz frequency range. The HMC518 provides 15 dB of small signal gain, 3 dB of noise figure and has an output IP3 greater than 23 dBm. The chip can easily be integrated into hybrid or MCM assemblies due to its small size. All data is tested with the chip in a 50 Ohm test fixture connected via 0.075mm (3 mil) ribbon bonds of minimal length 0.31 mm (12 mil). Two 0.025 mm (1 mil) diameter bondwires may also be used to make the RFIN and RFOUT connections.

If 0.254mm (10 mil) thick alumina thin film substrates must be used, the die should be raised 0.150mm (6 mils) so that the surface of the die is coplanar with the surface of the substrate. One way to accomplish this is to attach the 0.102mm (4 mil) thick die to a 0.150mm (6 mil) thick molybdenum heat spreader (moly-tab) which is then attached to the ground plane (Figure 2). Microstrip substrates should brought as close to the die as possible in order to minimize bond wire length. Typical die-to-substrate spacing is 0.076mm to 0.152 mm (3 to 6 mils). Gold ribbon of 0.075 mm (3 mils) width and minimum < 0.31 mm (
