HMC565
v03.1217 LOW NOISE AMPLIFIERS -CHIP GaAs PHEMT MMIC LOW NOISE
AMPLIFIER, 6 -20 GHz
Typical Applications Features The HMC565 is ideal for use as a LNA or driver amplifier for: Noise Figure: 2.3 dB • Point-to-Point Radios OIP3: 20 dBm • Point-to-Multi-Point Radios & VSAT Single Supply: +3V @ 53 mA • Test Equipment and Sensors 50 Ohm Matched Input/Output • Military & Space Small size: 2.53 x 0.98 x 0.10 mm Functional Diagram General Description Gain: 22 dB The HMC565 is a high dynamic range GaAs PHEMT
MMIC Low Noise Amplifier (LNA) chip which operates
from 6 to 20 GHz. The HMC565 features 22 dB of small
signal gain, 2.3 dB of noise figure and has a consistent
IP3 of 20 dBm across the operating band. This selfbiased LNA is ideal for hybrid and MCM assemblies
due to its compact size, wideband performance, single
+3V supply operation, and DC blocked RF I/O’s. All
data is measured with the chip in a 50 Ohm test
fixture connected via two 0.025 mm (1 mil) diameter
bondwires of minimal length 0.31 mm (12 mil). Electrical Specifications, TA = +25° C, Vdd 1, 2, 3 = +3V
