HMC518
v02.0217 LOW NOISE AMPLIFIERS -CHIP GaAs pHEMT MMIC LOW NOISE
AMPLIFIER, 20 -32 GHz
Typical Applications Features The HMC518 is ideal for use as a LNA or driver amplifier for: Noise Figure: 3 dB • Point-to-Point Radios OIP3: 23 dBm • Point-to-Multi-Point Radios & VSAT Single Supply: +3V @ 65 mA • Test Equipment and Sensors 50 Ohm Matched Input/Output • Military & Space Die Size: 2.27 x 1.32 x 0.1 mm Functional Diagram General Description Gain: 15 dB 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. Electrical Specifications, TA = +25° C, Vdd 1, 2, 3 = +3V
